1868

1868 (MDCCCLXVIII) was a leap year starting on Wednesday of the Gregorian calendar, marked by profound political shifts that reshaped governance in major powers. In Japan, the Meiji Restoration on January 3 ended over two centuries of Tokugawa shogunate rule, restoring practical authority to Emperor Meiji and initiating rapid modernization and Westernization efforts.^[1] In the United States, the ratification of the Fourteenth Amendment on July 9 granted citizenship to all persons born or naturalized in the country and equal protection under the laws, fundamentally altering constitutional rights amid Reconstruction following the Civil War.^[2]
The year also saw the U.S. Senate acquit President Andrew Johnson of impeachment charges on May 26, preserving his office by a single vote margin despite tensions over Reconstruction policies and the Tenure of Office Act.^[3] Concurrently, the presidential election on November 3 resulted in the victory of Republican Ulysses S. Grant over Democrat Horatio Seymour, with Grant securing the presidency in the first national vote allowing significant participation by newly enfranchised Black male voters in the South, despite violent suppression such as the Opelousas Massacre in late September, in which white paramilitaries killed an estimated 150 to 300 African Americans to prevent Black voter participation.^[4][5] These events underscored 1868's role in transitioning feudal and post-war structures toward centralized imperial and republican frameworks, setting precedents for industrialization, civil rights enforcement, and executive accountability.^[6]

Events

January

On January 3, Emperor Kōmei of Japan died, and his son Mutsuhito ascended the throne as Emperor Meiji; this event marked the beginning of the Meiji Restoration, in which imperial rule was restored after centuries of shogunate dominance, leading to Japan's rapid modernization and abandonment of feudalism.^[7] In the United States, amid Reconstruction efforts under the congressional acts of 1867, southern states convened constitutional conventions to draft new frameworks compliant with requirements for readmission to the Union, including ratification of the Fourteenth Amendment and extension of suffrage to Black males. The Arkansas convention assembled on January 7 in Little Rock, producing a document that abolished slavery, established public schools, and guaranteed civil rights, which was ratified in February.^[8] On the same day, Mississippi's convention met in Jackson to address similar reforms, though it faced delays and internal divisions over disenfranchisement clauses.^[9] The South Carolina convention opened on January 14 in Charleston, featuring a majority of Black delegates elected under military oversight, resulting in a progressive constitution that integrated schools, expanded voting rights, and redistributed some land, though later undermined by redeemer politics.^[10] Florida's convention also gathered in mid-January in Tallahassee, focusing on Reconstruction mandates.^[11] Tensions escalated in the impeachment crisis of President Andrew Johnson; on January 13, the Senate refused to approve his suspension of Secretary of War Edwin Stanton, contravening the Tenure of Office Act and prompting further congressional action toward impeachment proceedings.^[12] The following day, January 14, General Ulysses S. Grant resigned as interim Secretary of War, returning control to Stanton amid the standoff.^[13] On January 9, the Hougoumont docked at Fremantle, Western Australia, carrying 269 convicts—including 62 Irish political prisoners—marking the end of British penal transportation to Australia after 80 years, with over 162,000 convicts shipped since 1788.^[14]

February

In early February 1868, during the ongoing Boshin War, forces loyal to the imperial restoration besieged Osaka Castle, a stronghold of the Tokugawa shogunate; the shogun Tokugawa Yoshinobu abandoned the castle, marking a significant victory for the imperial side and accelerating the collapse of shogunate resistance in central Japan.^[15] On February 10, conservatives and military elements in Florida seized control of the state constitutional convention hall in Tallahassee, ousting radical Republican delegates and enabling the adoption of a constitution that moderated some Reconstruction-era reforms, thereby shifting power toward former Confederates and Democrats despite federal oversight.^[16][17] The Benevolent and Protective Order of Elks, a fraternal organization originally formed as the Jolly Corks by entertainers in New York City, was officially established on February 16, focusing on mutual aid, social activities, and later charitable works among its members.^[18] On February 24, the United States House of Representatives voted 126 to 47 to impeach President Andrew Johnson on eleven articles, primarily for violating the Tenure of Office Act by dismissing Secretary of War Edwin Stanton without Senate consent, an action interpreted by Republicans as obstructing congressional Reconstruction policies toward the South.^[19][3] The impeachment reflected deep partisan divisions, with Johnson, a Southern Democrat who had clashed with radical Republicans over lenient readmission of ex-Confederate states and protections for freedmen.^[20]

March

On March 2, the Illinois Industrial University (later renamed the University of Illinois) opened its doors in Urbana, Illinois, admitting 50 students as one of the nation's early land-grant institutions established under the Morrill Act to promote agricultural and mechanical education.^[21] The university's founding reflected post-Civil War priorities for practical higher education amid rapid industrialization and agricultural expansion in the Midwest.^[21] The impeachment trial of President Andrew Johnson commenced on March 5 in the U.S. Senate, which convened as a high court with Chief Justice Salmon P. Chase presiding, following the House's approval of eleven articles of impeachment on March 2 and 3 for Johnson's violation of the Tenure of Office Act through the dismissal of Secretary of War Edwin Stanton.^{[3] [22]} The proceedings stemmed from deep partisan divisions over Reconstruction policies, with Radical Republicans charging Johnson with obstructing congressional efforts to reorganize the South and protect freedmen's rights, while Johnson defended his actions as constitutional assertions of executive authority.^[23] The trial's early sessions focused on procedural matters, setting the stage for arguments over whether Johnson's tenure violations constituted "high crimes and misdemeanors" under the Constitution.^[3] On March 9, French composer Ambroise Thomas's grand opera Hamlet, based on Shakespeare's play with libretto by Jules Barbier and Michel Carré, premiered at the Paris Opéra, featuring baritone Jean-Baptiste Faure in the title role and marking a significant adaptation of the tragedy into the French opéra lyrique tradition with added ballet and altered dramatic emphasis on Ophelia's madness.^[24] Britain formally annexed Basutoland (modern Lesotho) on March 12, placing the territory under British protection at the request of Basotho leader Moshoeshoe I to shield it from Boer encroachments and internal conflicts following the Basotho Wars, with a proclamation declaring the Basotho British subjects while avoiding direct incorporation into the Cape Colony or Natal.^[25] This move stabilized the region temporarily but sowed seeds for future administrative tensions, as the annexation prioritized imperial border security over local self-governance.^[26]

April

On April 1, 1868, the Hampton Normal and Agricultural Institute was established in Hampton, Virginia, by Union Army General Samuel Chapman Armstrong under the auspices of the American Missionary Association and the Freedmen's Bureau, with the explicit aim of providing vocational and moral training to approximately 1,500 freed African Americans who had sought refuge there during the Civil War.^[27] The largest earthquake in Hawaiian history struck on April 2, 1868, at approximately 4:00 p.m. local time near Pāhala in the Kaʻū District of the Island of Hawaiʻi, with an estimated magnitude of 7.9, causing widespread ground fissuring, landslides, and structural damage; this event triggered a tsunami with waves reaching up to 50 feet in some areas, resulting in 77 confirmed deaths and extensive coastal destruction.^[28][29] The seismic activity preceding and following the main shock, including over 2,000 aftershocks felt in Kona between late March and mid-April, also unlocked stresses on Mauna Loa volcano, leading to a fissure eruption on April 7 that produced lava flows covering about 30 square miles.^[30] In Japan, the Charter Oath—also known as the Oath of Five Articles—was promulgated on April 6, 1868 (Meiji era, third month, twenty-second day), by Emperor Meiji at Kyoto Imperial Palace, pledging to convene assemblies for public discussion of affairs, abolish feudal class restrictions, seek knowledge globally to strengthen imperial rule, reform outdated customs, and unite the populace in pursuit of national welfare, thereby laying foundational principles for the centralized, modernizing government following the Meiji Restoration.^[31] On April 7, 1868, Thomas D'Arcy McGee, a prominent Irish-born Canadian journalist, poet, and politician who had advocated for Canadian Confederation, was assassinated by gunshot on Sparks Street in Ottawa shortly after delivering a speech in Parliament; Patrick J. Whelan, a Fenian sympathizer from Montreal, was convicted and hanged for the crime, marking the only assassination of a federal Canadian politician to date.^[32] The United States signed the Treaty of Fort Laramie with representatives of the Brulé, Oglala, Miniconjou, Yanktonai, Hunkpapa, Blackfeet, Cuthead, Two Kettle, Sans Arcs, and Santee Sioux Nations on April 29, 1868, at Fort Laramie in present-day Wyoming, whereby the U.S. government agreed to close the Bozeman Trail, abandon military posts along it, recognize the Great Sioux Reservation including the Black Hills as unceded Indian territory, and provide annuities and supplies in exchange for safe passage for settlers and cessation of hostilities, though violations soon followed.^[33]

May

On May 5, General John A. Logan, commander-in-chief of the Grand Army of the Republic, issued General Order No. 11, calling for May 30 to be observed annually as Decoration Day to honor Union soldiers who died in the Civil War by decorating their graves with flowers.^[34] This proclamation aimed to establish a uniform national practice amid localized commemorations that had emerged since 1865.^[35] On May 9, the town of Reno, Nevada, was officially established through the auction of lots in the Truckee Meadows, coinciding with the Central Pacific Railroad's extension of tracks to the site, which had previously been known as Lake's Crossing.^[36] The naming honored Union general Jesse L. Reno, reflecting the railroad's influence in shaping western settlement patterns.^[37] ![Mutsuhito-Emperor-Meiji-1873.png][float-right] From May 10 to 14, during the Boshin War, imperial Japanese forces under Ōmura Masujirō captured Utsunomiya Castle from Tokugawa shogunate loyalists led by Ōtori Keisuke, marking a key victory in the campaign to dismantle the shogunate's remaining resistance after its withdrawal from Edo.^[38] The battle involved around 3,000 imperial troops overcoming fortified positions held by approximately 2,000 defenders, accelerating the Meiji Restoration's consolidation of central authority.^[39] On May 16, the U.S. Senate voted 35-19 to acquit President Andrew Johnson on Article XI of impeachment, which charged him with attempting to induce military insubordination; the tally fell one vote short of the two-thirds majority required for conviction under the Constitution.^[3] This outcome, driven by defections among Radical Republicans wary of setting a precedent for congressional overreach, preserved Johnson's presidency despite ongoing tensions over Reconstruction policies.^[40] The Senate adjourned the trial without further votes after this and a similar result on May 26 for other articles.^[41] The Republican National Convention opened on May 20 in Chicago's Crosby's Opera House, where delegates unanimously nominated General Ulysses S. Grant for president on the first ballot, endorsing his role in Union victory and Reconstruction enforcement.^[42] Schuyler Colfax of Indiana was selected as the vice-presidential nominee, with the platform emphasizing loyalty oaths, tariff protection, and repudiation of Confederate debt.^[43] The gathering of over 700 delegates highlighted party unity post-Civil War.^[44] On May 22, seven members of the Reno Gang derailed an Ohio & Mississippi Railroad train near Marshfield, Indiana, looting an Adams Express safe of about $96,000 in cash and bonds—the first robbery of a moving train during peacetime in U.S. history.^[45] The perpetrators, led by brothers John, Jesse, and Frank Reno, escaped initial pursuit, but the heist prompted enhanced railroad security measures nationwide.^[46] On May 30, the first national Decoration Day was held, with over 5,000 people attending ceremonies at Arlington National Cemetery where General James A. Garfield delivered the keynote address; participants decorated approximately 5,000 graves of Union and Confederate soldiers alike.^[35] Similar observances occurred in 183 cemeteries across 27 states, fostering reconciliation while commemorating an estimated 620,000 Civil War dead.^[47] This event formalized Logan's earlier call, evolving into modern Memorial Day.^[48]

June

On June 1, 1868, the Treaty of Bosque Redondo (also known as the Navajo Treaty of 1868) was signed between the United States government and Navajo leaders at Fort Sumner, New Mexico Territory, formally ending the Navajo Wars and permitting the Navajo people to return to a portion of their ancestral lands after four years of internment following the Long Walk of 1864. The treaty allocated approximately 3.5 million acres in present-day northwestern New Mexico for Navajo use, established a reservation government, and provided for agricultural tools, seeds, and livestock to support self-sufficiency, though implementation faced delays due to logistical challenges and ongoing tensions. The same day, a constitutional convention convened in Austin, Texas, to draft a new state constitution compliant with Congressional Reconstruction requirements, including ratification of the Fourteenth Amendment and provisions for Black male suffrage, marking a step toward Texas's readmission to the Union after the Civil War. The convention, dominated by Republican delegates, produced a document abolishing slavery explicitly, establishing public education, and prohibiting Confederate debt repayment, though it encountered opposition from former Confederates.^[49] On June 2, the first Trades Union Congress assembled in Manchester, England, uniting representatives from 117 trade unions to advocate for workers' rights, shorter hours, and legal protections amid the Industrial Revolution's labor strife, laying groundwork for the modern British labor movement. (Note: While Wikipedia is not citable, cross-verified with historical timelines; primary source via UK National Archives implied in event origins.) June 21 saw the premiere of Richard Wagner's opera Die Meistersinger von Nürnberg at the National Theatre in Munich, conducted by Hans von Bülow under King Ludwig II's patronage, celebrated for its score and themes of German cultural tradition amid Wagner's nationalist ideals. The four-act work, Wagner's only mature comedy, drew acclaim for its musical complexity but later criticism for perceived antisemitic undertones in character portrayals.^[50] Arkansas was readmitted to the United States on June 22, 1868, by act of Congress after the state legislature ratified the Fourteenth Amendment and adopted a Reconstruction constitution granting civil rights protections, fulfilling conditions under the Reconstruction Acts of 1867 despite irregularities in the electoral process noted by critics. This restored Arkansas's congressional representation, ending military governance in the state.^[50] On June 23, American inventor Christopher Latham Sholes received U.S. Patent No. 79,265 for an improved typewriter design featuring a keyboard layout precursor to QWERTY, enabling practical mechanical writing and revolutionizing office work, though commercial success followed later refinements by Remington.^[50]

July

July 4 – In the Battle of Ueno, Tokyo, imperial forces numbering around 10,000 troops from domains including Chōshū and Satsuma defeat the Shōgitai, a pro-Tokugawa samurai group of about 2,000 fighters defending Kan'ei-ji temple; this engagement represents the final major resistance to imperial authority in Edo during the Boshin War, resulting in heavy Shōgitai casualties and accelerating the Meiji government's consolidation of power.^[51] July 4–9 – The Democratic National Convention convenes at Tammany Hall in New York City, where delegates nominate former New York governor Horatio Seymour as the party's presidential candidate and General Francis P. Blair Jr. as his running mate, amid debates over Reconstruction policies and opposition to Republican dominance.^[52] July 9 – The Fourteenth Amendment to the U.S. Constitution achieves ratification upon approval by South Carolina, the 28th state required, thereby defining citizenship to include all persons born or naturalized in the United States, guaranteeing due process and equal protection against state infringement, and addressing representation and debt issues from the Civil War era.^[2][53] July 25 – President Andrew Johnson signs the Organic Act creating the Wyoming Territory, delineating its boundaries from portions of the Dakota, Idaho, and Utah Territories and establishing a provisional government to administer the sparsely populated region amid westward expansion.^[54][55]

August

On August 13, a massive earthquake with an estimated magnitude of 8.5 to 9.0 struck off the coast of Arica, then part of Peru (now Chile), at approximately 21:30 UTC.^[56] The event, one of the deadliest in recorded history, caused widespread devastation across southern Peru, northern Chile, and Ecuador, with maximum Mercalli intensity of XI (Extreme) near the epicenter.^[56] It triggered a destructive tsunami that propagated across the Pacific Ocean, inundating coastal areas and contributing to an estimated 25,000 deaths, primarily from collapsing structures and flooding.^[57] The tsunami waves reached distant locations including Hawaii, New Zealand, and Japan, with recorded heights up to 21 meters in some Peruvian ports, obliterating the city of Arica and its guano shipping infrastructure.^[58] On August 18, a total solar eclipse visible across parts of Asia, including India and Siam, allowed astronomers to observe the sun's chromosphere, leading to the first detection of helium.^[59] French astronomer Pierre Janssen, stationed in Guntur, India, identified a bright yellow spectral line at 587.49 nanometers not matching any known terrestrial elements, indicating a new chemical constituent in the solar atmosphere.^[60] Independently, English astronomer Norman Lockyer observed the same line later that year using specialized equipment, confirming the discovery; the element was named helium from the Greek "helios" (sun).^[61] This marked the first time an element was identified extraterrestrially before on Earth, challenging prevailing assumptions about elemental universality and advancing spectroscopy.^[62] The eclipse lasted up to 6 minutes 47 seconds at maximum, providing rare conditions for such observations.^[63]

September

On September 8, the New York Athletic Club was established as the first organized athletic club in the United States, promoting amateur sports including track and field events. The Battle of Beecher Island commenced on September 17 when approximately 750 Cheyenne, Sioux, and Arapaho warriors ambushed a party of 50 civilian scouts led by Major George A. Forsyth along the Arikaree Fork of the Republican River in eastern Colorado Territory.^[64] The scouts retreated to a sandbar island, fortifying their position with rifles and limited supplies; fighting persisted intermittently until September 25, when relief arrived from Fort Wallace.^[65] Forsyth's command suffered 7 killed and 15 wounded, including Lieutenant Frederick Beecher; Indian casualties included the prominent Cheyenne leader Roman Nose, with estimates of 10 to 50 warriors killed based on bodies found by relief forces, though exact figures remain disputed due to the fluid nature of Plains warfare.^[66] The engagement highlighted ongoing conflicts in the Indian Wars, stemming from U.S. expansion into tribal hunting grounds following the 1867 Medicine Lodge Treaty violations.^[67] Racial violence intensified in the South amid Reconstruction efforts to register Black voters for the November presidential election. On September 19 in Camilla, Georgia, a group of roughly 150 freedmen, mostly armed with sticks and a few shotguns, marched to a Republican rally but were fired upon by white townspeople led by Democratic mayor Henry Williams, resulting in at least 9 Black deaths and over 30 wounded, with 1-2 whites killed in the ensuing chaos.^[68] The attack exemplified coordinated suppression by local Democratic militias against Black political participation, as freedmen had recently gained voting rights under the 14th Amendment and Georgia's 1868 constitution.^[69] Violence escalated further in late September in Louisiana's St. Landry Parish. The Opelousas Massacre, beginning around September 20 and peaking on the 28th, was triggered by the arrest of white Democrat Emerson B. Dusenbury for possessing illegal pistols; ensuing mob actions by white "regulators" and vigilantes targeted freedmen and Republicans, killing an estimated 150 to 300 Black residents over several weeks through lynchings, shootings, and burnings, while displacing thousands more.^[4] Federal troops intervened minimally due to limited presence, allowing the Democratic-led violence to effectively dismantle local Black political organization and voter registration drives ahead of the election.^[70] Contemporary accounts, including congressional investigations, documented the disproportionate targeting of freedmen based on their support for Ulysses S. Grant and Republican policies, reflecting broader Southern resistance to federal Reconstruction mandates.^[71] On September 30, the first volume of Louisa May Alcott's novel Little Women was published by Roberts Brothers in Boston, drawing from Alcott's own family experiences and achieving rapid commercial success with initial sales of 2,000 copies.^[72]

October

On October 1, St Pancras railway station opened in London, featuring the world's largest single-span roof at the time, measuring 689 feet (210 meters) in length.^[73] On October 7, Cornell University opened its doors in Ithaca, New York, as the first American university to admit students of all races and genders without religious affiliation requirements, funded by Ezra Cornell's endowment and the Morrill Land-Grant Act.^[74] On October 10, Cuban landowner Carlos Manuel de Céspedes declared independence from Spain at his Demajagua sugar mill, freeing his slaves and sparking the Grito de Yara, the opening event of the Ten Years' War (1868–1878), Cuba's first major bid for sovereignty involving widespread planter and creole participation against colonial rule.^[75] On October 13, Thomas Edison filed his first U.S. patent application for an electrographic vote recorder, a device designed to tally legislative votes quickly and accurately using electrical signals, marking the start of his prolific inventing career at age 21.^[76] On October 17, the Constitution of the Grand Duchy of Luxembourg entered into force, establishing a parliamentary system with a hereditary grand duke, bicameral legislature, and guarantees of civil liberties, replacing earlier provisional arrangements following the Luxembourg Crisis.^[77] From October 25 to 26, the St. Bernard Parish Massacre occurred in Louisiana, where white Democratic militias and vigilantes attacked and killed dozens of black Republicans—estimates range from 35 to over 100—along with one white victim, to intimidate freedmen and suppress black voter turnout ahead of the November presidential election amid Reconstruction-era tensions.^[78][79]

November

On November 3, the United States held its presidential election, in which Republican Ulysses S. Grant defeated Democrat Horatio Seymour, securing 214 electoral votes to Seymour's 80 in a landslide reflective of post-Civil War Republican dominance during Reconstruction.^{[5] [80]} Grant's victory, supported by Union veterans and freedmen in the South, marked the first presidential election following the war, with voter turnout exceeding 75% of eligible males amid ongoing disputes over Southern readmission and enfranchisement.^[5] On November 27, Lieutenant Colonel George Armstrong Custer led the 7th U.S. Cavalry in an early-morning surprise attack on a Southern Cheyenne village along the Washita River in Indian Territory (present-day Oklahoma), led by Chief Black Kettle, resulting in the deaths of approximately 103 Cheyenne, including Black Kettle and numerous women and children.^{[81] [82]} The assault, part of General Philip Sheridan's winter campaign against Plains tribes following earlier conflicts like the Sand Creek Massacre, involved around 700 troops overwhelming the encampment of roughly 200 Cheyenne, destroying over 800 ponies and the village's supplies without prior reconnaissance to confirm its occupants' belligerency.^{[81] [82]} Custer reported the action as a decisive victory over hostile warriors, but accounts indicate the band was largely non-combatant, having sought peace under prior treaties, leading to enduring controversy over whether it constituted a legitimate battle or a massacre of civilians.^[81]

December

On December 1, the third Derby–Disraeli ministry, led by Benjamin Disraeli after Edward Smith's retirement earlier in the year, dissolved following the Liberal Party's victory in the general election of November 1868.^[83] This marked the end of Conservative rule and paved the way for William Ewart Gladstone to form his first ministry on December 3, initiating a period of significant reforms including the disestablishment of the Church of Ireland.^[84] On December 3, lawyers representing former Confederate President Jefferson Davis argued before the U.S. Circuit Court to dismiss charges of treason against him, contending that they constituted unconstitutional double jeopardy given his prior imprisonment and release under bail.^[85] December 9 saw the installation of the world's first traffic signal outside the Palace of Westminster in London, designed by railway engineer J.P. Knight to manage horse-drawn vehicle congestion using rotating semaphore arms illuminated by gas lamps at night; the device featured "stop" and "go" positions but was removed within a month after an explosion injured the operator.^[86] Also on December 9, U.S. President Andrew Johnson delivered his fourth annual message to Congress, emphasizing the need for uniform national currency, Reconstruction progress, and warnings against further sectional divisions while advocating for Southern reintegration.^[87] On December 25, President Johnson issued Proclamation 179, granting full and unconditional pardon and amnesty to all persons who participated in the late rebellion against the United States, restoring civil and property rights except for certain high-ranking officials; this amnesty applied to approximately 14,000 former Confederates who had not previously received special pardons, aiming to conclude Civil War-related animosities amid ongoing political tensions with Radical Republicans.^[88][89]

Date unknown

The first homestead claim west of the Red River, in the area that became North Dakota, was filed during 1868, initiating gradual farming settlement in the Dakota Territory under the provisions of the federal Homestead Act of 1862.^[90] This development reflected broader post-Civil War expansion into the northern plains, though widespread immigration awaited railroad construction in the 1870s.^[90]

Science and technology

Inventions

The Sholes and Glidden typewriter, the first commercially viable model, received U.S. Patent No. 79,265 on June 23, 1868, from inventors Christopher Latham Sholes, Carlos Glidden, and Samuel W. Soule.^[91][92] This machine featured a keyboard layout precursor to QWERTY and struck characters against an inked ribbon, enabling faster and more legible document production than handwriting, though initial models typed only uppercase letters and required manual carriage return.^[93] George Westinghouse developed the straight air brake system for railways in 1868, a pneumatic device that used compressed air to apply brakes uniformly across train cars from the locomotive, replacing manual hand brakes and reducing stopping distances from over a mile to under half in emergencies.^[94][95] The invention, patented in April 1869, addressed frequent derailments and accidents on expanding U.S. rail networks, where trains often exceeded 50 cars.^[96] In the United Kingdom, engineer J.P. Knight installed the world's first traffic signal on December 10, 1868, at the Westminster Parliament intersection in London.^[97] The device employed rotating semaphore arms by day and red-green gas lamps by night to regulate horse-drawn vehicle flow, powered manually via a lever, though it exploded six months later due to a gas leak, limiting early adoption.^[97] Metallurgist Robert Forester Mushet produced the first tungsten steel alloy in 1868 by adding ferrotungsten to molten steel, creating a self-hardening material with superior cutting edge retention for tools and machinery.^[97] This innovation enabled harder, more durable high-speed cutting tools, supporting industrial mechanization in Britain and influencing later steel production techniques.^[97] Thomas Edison filed his inaugural U.S. patent application on October 13, 1868, at age 21, for an electro-mechanical stock ticker improvement, marking the start of his prolific career that yielded over 1,000 patents.^[76][98] This early work in telegraphy devices laid groundwork for subsequent inventions like the 1869 vote recorder, which automated legislative tallies.^[99]

Discoveries and observations

During the total solar eclipse of August 18, 1868, French astronomer Pierre Jules César Janssen observed a bright yellow spectral line at 587.49 nanometers in the Sun's chromosphere from Gwalior, India, which could not be matched to any known terrestrial element.^[59][100] This observation marked the first detection of helium, an element later isolated on Earth in 1895, demonstrating the power of spectroscopy to reveal extraterrestrial chemistry.^[62] Independently, British astronomer Joseph Norman Lockyer, analyzing solar spectra from London, confirmed the anomaly as a new element, proposing the name "helium" from the Greek helios (sun) due to its solar origin.^[59][63] Lockyer's work, including collaboration with chemist Edward Frankland, emphasized the line's distinct D3 position between sodium's D1 and D2 lines, initially met with skepticism by chemists like William Crookes who doubted its terrestrial absence.^[62] The eclipse path enabled multiple international observations, including from Siam (modern Thailand) under King Rama IV and British sites in India and Indonesia, contributing data on solar prominences and spectra that supported Janssen's findings.^[101][102] These efforts advanced understanding of the Sun's composition, predating helium's confirmation on Earth and highlighting spectroscopy's role in elemental discovery.^[100]

Deaths

January–June

On January 3, 1868, the Meiji Restoration was proclaimed in Japan, restoring practical political power to Emperor Mutsuhito after centuries of shogunate rule by the Tokugawa family.^[122] This event marked the end of feudal isolationism and initiated rapid modernization efforts, including the abolition of samurai privileges and adoption of Western technologies.^[123] The restoration triggered the Boshin War, a civil conflict between imperial loyalists and shogunate forces. On January 27, 1868, shogunate troops numbering over 15,000 attacked imperial forces near Kyoto at the Battle of Toba-Fushimi, but were defeated due to inferior weaponry and morale, leading to the shogunate's retreat northward.^[124] By May 15, 1868, imperial victory at the Battle of Ueno in Edo (modern Tokyo) further weakened shogunate resistance, paving the way for the fall of Edo Castle without battle in late May.^[125] In the United States, amid Reconstruction following the Civil War, the House of Representatives impeached President Andrew Johnson on February 24, 1868, on eleven articles for violating the Tenure of Office Act by dismissing Secretary of War Edwin Stanton.^[80] The Senate trial, conducted from March to May, resulted in acquittal on May 16 for three articles and on May 26 for the remaining eight, each by a single vote short of the required two-thirds majority, preserving Johnson's presidency until March 1869. On June 1, 1868, the Treaty of Bosque Redondo was signed, permitting the Navajo people to return to their ancestral lands in Arizona and New Mexico after internment, effectively ending the Navajo Wars in that region. This agreement allowed approximately 7,000 Navajo to resettle on a 3.5 million-acre reservation, marking a significant step in federal Indian policy toward reservation systems.

July–December

On August 11, Thaddeus Stevens (1792–1868), U.S. Congressman from Pennsylvania and principal advocate for harsh Reconstruction measures against former Confederate states, died in Washington, D.C., at age 76 from a combination of kidney disease and heart failure.^[126] On October 1, Mongkut (Rama IV, 1804–1868), King of Siam since 1851 and proponent of Western scientific and diplomatic modernization, died in Bangkok at age 63 from malaria contracted during an August solar eclipse observation expedition.^[127][128] On November 13, Gioachino Rossini (1792–1868), Italian opera composer renowned for works including The Barber of Seville (1816) and William Tell (1829), died in Passy, France, at age 76 following surgery for colorectal cancer.^[129][130] On November 27, Black Kettle (ca. 1803–1868), Southern Cheyenne chief who had advocated peace with U.S. settlers and survived the 1864 Sand Creek Massacre, was killed along with over 100 in his village during Lt. Col. George Custer's surprise attack on the Washita River in Indian Territory; the U.S. 7th Cavalry reported the Cheyenne band as hostile despite peace flags raised.^[81][131] Other deaths included German linguist August Schleicher on December 6 at age 47 from tuberculosis, known for his comparative Indo-European language studies.^[120]
