1660

1660 was the year in which the English monarchy was restored under Charles II, who returned from exile to end the eleven-year republican interregnum established after the execution of his father, Charles I, in 1649.^[1][2]
The collapse of Oliver Cromwell's Protectorate under his son Richard prompted General George Monck to march on London in February, leading to the reinstatement of the Rump Parliament and the convening of the Convention Parliament in April, which voted to recall Charles and issued the Declaration of Breda outlining terms for his return.^[3][4] Charles landed at Dover on 25 May amid naval salutes and proceeded to London on 29 May, greeted by massive crowds strewing flowers along his route to Whitehall.^[4][5]
The Restoration Parliament subsequently executed ten regicides involved in Charles I's death and passed the Act of Indemnity and Oblivion to pardon most others, while the royal charter later formalized the Royal Society's founding meetings from late 1660, promoting empirical scientific inquiry.^[3] In Northern Europe, the Treaty of Copenhagen ended the Second Northern War, with Sweden retaining gains from Denmark-Norway including Scania but returning other territories seized during the conflict.^[6]

Historical Context

Decline of the English Commonwealth

Following Oliver Cromwell's death on September 3, 1658, his son Richard assumed the role of Lord Protector but quickly proved unable to mediate between the army's radical elements and a fractious Parliament, exposing the fragility of the republican structure.^[7] The recalled Rump Parliament, reinstated in May 1659 after its earlier dissolution in 1653, clashed with army officers over pay arrears and political control, culminating in the Rump's forcible dissolution by military decree on October 13, 1659.^[8] This triggered a cascade of factional strife, including the short-lived Committee of Safety and rival army commands under figures like John Lambert, which fragmented authority and bred widespread anarchy, as local militias and petitions for stability proliferated amid fears of renewed civil war.^[9] Religious impositions under the Commonwealth exacerbated these divisions, as Puritan authorities enforced strict moral codes—such as bans on theater, sports on the Sabbath, and Christmas celebrations—that alienated moderate Anglicans, gentry, and merchants who prioritized traditional social liberties over sectarian reforms.^[10] After the Restoration, nonconformist persecution continued, exemplified by the arrest of Baptist preacher John Bunyan on November 12, 1660, for unlicensed preaching, leading to his 12-year imprisonment during which he wrote major works like Pilgrim's Progress.^[11] While Oliver Cromwell had extended limited toleration to Protestants beyond Presbyterians, the regime's failure to forge a unified national church, coupled with the rise of radical groups like the Fifth Monarchists in 1653, deepened schisms; empirical records show petitions from counties decrying "enthusiasm" and demanding episcopal restoration, reflecting broad resentment against perceived theocratic overreach that undermined the regime's claim to represent the "Good Old Cause" of liberty.^[12] This alienation eroded civilian support, leaving governance reliant on coercive army rule, which itself splintered due to unpaid troops and ideological rifts. Military commitments further strained resources, with ongoing occupations in Scotland and Ireland alongside costly naval wars—the First Anglo-Dutch War (1652–1654) and interventions against Spain from 1655—imposing heavy taxation and diverting funds from domestic stability, as army strength peaked at over 50,000 men by 1658 yet could not prevent internal revolts like the 1655 Penruddock uprising.^[13] The Protectorate's fiscal burdens, including arrears exceeding £2 million by late 1659, fueled mutinies and underscored the causal mismatch between expansionist ambitions and a legitimacy-starved republic unable to sustain prosperity or consent. In response to this chaos, General George Monck, commanding forces in Scotland, marched south on January 1, 1660, with 5,000–6,000 troops, entering London on February 3 to disband radical elements, reinstate the Rump (with purged royalist-exclusion members readmitted by February 21), and enforce order through pragmatic constitutionalism rather than ideological purity.^[14] Monck's actions, driven by recognition of the regime's exhaustion and public yearning for settled governance, pragmatically paved the way for monarchical restoration without immediate bloodshed, highlighting the republic's inherent instability absent broad-based legitimacy.^[8]

European Geopolitical Landscape

The Peace of Westphalia in 1648 concluded the Thirty Years' War, marking a shift in European power dynamics by recognizing the independence of the Dutch Republic and granting greater autonomy to German principalities, which diminished the Holy Roman Empire's centralized Habsburg authority.^[15] This fragmentation weakened Habsburg influence in Central Europe, as territories like Bavaria and Saxony gained sovereignty, contributing to a decentralized German landscape where imperial cohesion eroded further by the 1660s.^[16] Meanwhile, France under the young Louis XIV began asserting dominance, bolstered by Cardinal Mazarin's diplomacy; Louis's marriage to Maria Theresa of Spain on June 9, 1660, symbolized reconciliation with Habsburg Spain while positioning France to exploit imperial divisions without immediate large-scale conflict.^[17] These developments established a balance where no continental power posed an imminent threat to English internal affairs, allowing the island kingdom relative insulation amid continental realignments.^[18] Peripheral conflicts persisted but remained contained, underscoring 1660's comparative stability after decades of widespread devastation, including the decisive Polish-Lithuanian victory at the Battle of Cudnów (October 14–November 2), which destroyed the southern Russian field army and shattered the Russian-Cossack alliance.^[19] The Portuguese Restoration War, initiated in 1640 to end Spanish Habsburg rule, continued with skirmishes along the Iberian frontier, including Portuguese victories at Ameixial (June 1663, though preparations mounted in 1660) that strained Spain without engulfing broader Europe.^[20] In the north, the Second Northern War (1655–1660) between Sweden and Denmark-Norway, involving Dutch and Polish support, culminated in the Treaty of Copenhagen on May 27, 1660, whereby Sweden relinquished Bornholm and Trøndelag, restoring pre-war borders and easing Baltic tensions.^[21] Such resolutions averted escalation into pan-European strife, contrasting the Thirty Years' War's scale and enabling powers to redirect resources toward internal consolidation rather than expansionist interventions. Mercantile rivalries between the Dutch Republic and England intensified through colonial and trade ventures, yet without erupting into war by 1660. The Dutch, in their Golden Age, dominated global commerce with the Dutch East India Company shipping over 1 million tons of goods annually by mid-century, including spices from Asia and slaves via Atlantic routes, while English efforts under the Navigation Acts of 1651 sought to capture shares in North American fur trade and Caribbean sugar production.^[22] These economic competitions laid groundwork for future Anglo-Dutch frictions but operated amid the post-Westphalian peace, where naval patrols focused on protection rather than conquest, further insulating Britain's restoration from external pressures.^[23]

Major Events

January–March

General George Monck, the parliamentary commander in Scotland, initiated the sequence of events leading to the Restoration by ordering his army to cross into England on January 1, 1660, from Coldstream, signaling a break from the republican regime's instability.^[24] This march reflected growing disillusionment with the Commonwealth's military factions and administrative failures, as Monck's forces, disciplined and loyal to him personally, avoided the internal purges plaguing England's garrisons.^[14] By early February, Monck's troops reached London without resistance, securing the city and displacing the Wallingford House junta—a radical army council that had dominated the Rump Parliament—thus restoring order and enabling parliamentary maneuvering free from direct military intimidation.^[24] Monck's restraint in not declaring for the king immediately preserved his leverage, pressuring the Rump to address demands for constitutional reform amid widespread royalist sympathies undiminished by years of republican governance.^[9] On February 11, Monck issued a letter to the Rump Parliament criticizing its tolerance of sectarian influences and effectively demanding the readmission of purged members to broaden representation.^[9] This culminated on February 21, when Monck oversaw the return of the "secluded" members—moderate Presbyterians excluded during Pride's Purge in 1648—reinstating the Long Parliament in a form closer to its pre-civil war composition.^[24] The restored body, numbering around 70 members initially, prioritized stability by affirming Monck's authority and preparing for elections, reflecting empirical recognition that the Rump's narrow base had eroded legitimacy after Oliver Cromwell's death and Richard Cromwell's ineffectual protectorate.^[25] The Long Parliament's brief revival ended on March 16, 1660, when it voted for its own dissolution and issued writs for a new Convention Parliament, explicitly acknowledging the exhaustion of republican experiments and the need for broader electoral consent to resolve the interregnum's constitutional vacuum.^[8] This act marked the definitive collapse of organized republican resistance, as the secluded members, many harboring royalist inclinations, facilitated a transition grounded in pragmatic assessment of public and military sentiment favoring monarchical restoration over continued oligarchic rule.^[26] Monck's orchestration of these parliamentary shifts, backed by his 7,000-strong army, underscored causal dynamics where military discipline trumped ideological fervor, paving the way for free elections that would overwhelmingly support Charles II's return.^[24]

April–June

On April 4, 1660, Charles, son of the executed King Charles I, issued the Declaration of Breda from his court in the Netherlands, promising a general pardon for actions during the interregnum, religious indulgence contingent on parliamentary consent, equitable resolution of disputed land titles from confiscations, and full payment of arrears to disband the [standing army](/page/standing army) without unrest.^[27][28] These pragmatic assurances addressed core demands from royalist sympathizers, naval officers, and soldiers weary of the Commonwealth's instability, signaling Charles's willingness to compromise on ideological absolutes to secure broad support.^[29] The Convention Parliament, elected after the Long Parliament's dissolution on March 16, convened on April 25 without royal writs, comprising mostly moderate royalists and Presbyterians seeking constitutional settlement over continued republican experiment.^[30] By May 1, it received the Declaration and debated restoration; on May 8, it resolved Charles as rightful king under the late king's authority, voting supplies for his return and passage of a resolution inviting him to England.^[29] This legislative pivot reflected widespread elite consensus for monarchical stability amid economic stagnation and factional deadlock under the Protectorate's collapse. Charles departed Scheveningen on May 23, landing at Dover on May 25 amid enthusiastic crowds and formal welcome by General George Monck, commander of the forces that had facilitated parliamentary recall.^[31] He progressed via Canterbury and Rochester, reaching London on May 29—his thirtieth birthday—where throngs lined streets for miles, strewing flowers and cheering in a display of popular fervor documented by eyewitness Samuel Pepys, who accompanied the royal yacht and described the unprecedented joy as evidence of national relief from civil war's lingering divisions.^[32][33] These events underscored the Restoration's momentum driven by voluntary acclaim rather than coercion, prioritizing practical governance over punitive retribution.

July–September

The Convention Parliament enacted the Indemnity and Oblivion Act on 29 August 1660, granting a general pardon for acts of treason and rebellion committed between 1640 and 1660, with explicit exceptions for those who had signed the death warrant of Charles I or participated in his trial and execution.^[34] This legislation targeted approximately 59 regicides identified as signatories to the 1649 warrant, mandating their prosecution for high treason while forgiving the broader populace to prevent vengeful chaos and facilitate monarchical restoration.^[35] The act's selective retribution reflected royalist insistence on causal accountability for the regicide, which had destabilized the realm by overturning hereditary succession, though it drew criticism from surviving republicans who viewed the exemptions as politically motivated purges rather than justice.^[36] Preparations for regicide trials intensified in the preceding months, with parliamentary committees reviewing evidence from the 1649 proceedings and issuing arrest warrants for fugitives like Major-Generals William Goffe and Edward Whalley, who fled to New England on 27 July.^[37] Empirical records from the High Court of Justice transcripts, preserved and re-examined, underscored the regicides' direct roles—such as Thomas Harrison's leadership in the New Model Army and advocacy for the king's trial—positioning their impending condemnations as proportionate response to the precedent of executing a sovereign without due parliamentary consent.^[38] Royal proclamations in July emphasized this framework, signaling to Parliament and the public that oblivion for minor offenders would coexist with exemplary punishment for the principals, thereby consolidating Charles II's authority without alienating moderate former parliamentarians.^[39] Radical intellectuals like John Milton, whose Eikonoklastes (1649) had defended the regicide and whose republican tracts continued circulating, faced peril during this period; after the Restoration, his writings were ordered burned by Parliament in June, and he evaded arrest by hiding through the summer, ultimately spared severe penalty through intercession by figures like Andrew Marvell and possibly his prior diplomatic service abroad.^[40] Milton's narrow escape highlighted tensions between punitive zeal and pragmatic leniency, as royal advisors weighed the risks of martyring prominent literati against the need for intellectual reconciliation; he later reflected in unpublished notes on the Restoration's fragility, critiquing it as a reversion to "slavish" governance absent popular sovereignty.^[41] This episode exemplified the act's broader intent: to excise ideological extremes fostering civil war while preserving a veneer of clemency, though dissenters decried it as selective amnesia favoring monarchical reprisal over republican equity.

October–December

On November 28, a group of twelve natural philosophers, including Christopher Wren, met at Gresham College in London following Wren's lecture on astronomy, resolving to form a collegium for the promotion of experimental learning and thereby establishing the Royal Society of London.^[42] This initiative arose amid the intellectual ferment following the collapse of the Puritan Commonwealth, prioritizing empirical observation and verification through repeatable experiments over scholastic authority or theological presuppositions, with early members such as Robert Boyle advocating mechanical philosophy grounded in observable causes.^[42] The society's formation marked a pivotal institutional commitment to methodical inquiry, influencing subsequent scientific advancements by institutionalizing collaborative verification detached from prior ideological constraints. Throughout October and November, Samuel Pepys, serving as a clerk in the naval office, recorded in his diary the resumption of administrative functions under the restored monarchy, including audits of naval stores, appointments to reformed commissions, and preparations for fleet maintenance, reflecting broader efforts to reconstitute bureaucratic mechanisms disrupted by the Interregnum.^[43] These entries detail mundane yet causal operations, such as reconciling accounts depleted by prior mismanagement and initiating contracts for ship repairs, underscoring the pragmatic reorientation toward functional governance rather than revolutionary experiments in statecraft.^[43] The Convention Parliament, convened in April to orchestrate the monarchy's restoration, concluded its session on December 29 when King Charles II prorogued it, having enacted legislation affirming hereditary succession, indemnifying supporters of the return, and laying groundwork for the coronation scheduled for the following year.^[44] This dissolution closed a provisional assembly that had prioritized legal continuity and royal prerogative over radical reforms, effectively bridging the Commonwealth's institutional void with precedents from before 1649 while averting further parliamentary overreach.^[44]

Date Unknown

The Puritan regime's ban on public theatrical performances, enacted in 1642 and enforced throughout the Interregnum, was lifted following the Restoration of the monarchy, enabling the reopening of theaters across England in 1660 after an 18-year suppression.^[45][46] This resumption of stage activity represented a deliberate rejection of Commonwealth-era cultural restrictions, which had viewed drama as morally corrosive and incompatible with religious discipline.^[47] Charles II, drawing from continental practices observed during his exile, authorized the revival of professional playhouses and extended royal patents to key managers such as Thomas Killigrew and William Davenant, formalizing two monopolistic acting companies—the King's Company and the Duke's Company—to produce and license plays under crown oversight.^[48] These developments facilitated the performance of new and revived works, including adaptations of pre-Commonwealth dramas, and introduced innovations like female actresses in women's roles, supplanting the prior convention of boy apprentices—a shift initially pioneered in late 1660 productions.^[49][50] In the colonial sphere, the restored Stuart government moved to consolidate overseas holdings by reaffirming proprietary charters and navigation policies, such as the 1660 Navigation Act, which mandated that colonial goods be transported in English vessels to bolster mercantile interests and curb Dutch competition, though implementation details lacked precise synchronization across distant territories.^[51] These measures underscored the monarchy's intent to integrate restored royal authority with existing transatlantic enterprises, without immediate disruptions to settlements in regions like Virginia and the Caribbean.^[52]

Scientific and Intellectual Developments

Founding of the Royal Society

The Royal Society emerged from informal gatherings of intellectuals in Oxford and London during the mid-17th century, which evolved into structured weekly meetings by the late 1650s amid the political transitions following the English Civil Wars.^[42] On 28 November 1660, twelve natural philosophers, including Christopher Wren and Robert Boyle, convened at Gresham College after Wren's astronomy lecture and resolved to form a permanent collegium dedicated to experimental inquiry into natural phenomena.^[42] This gathering, occurring shortly after the Restoration of the monarchy, marked the society's foundational moment, shifting from ad hoc discussions to an organized pursuit of knowledge through observation and testing.^[53] Unlike the preceding Commonwealth period, dominated by Puritan theological priorities that subordinated empirical pursuits to scriptural interpretation, the Royal Society emphasized firsthand verification over inherited authority.^[42] King Charles II formalized this approach by granting the society its first royal charter on 15 July 1662, incorporating it as "The Royal Society of London for Improving Natural Knowledge" and adopting the motto Nullius in verba—Latin for "take nobody's word for it"—to signify reliance on reproducible evidence rather than dogmatic assertion.^[42] The charter empowered the fellowship to conduct experiments, collect data, and disseminate findings, fostering a methodology rooted in causal mechanisms observable through controlled trials.^[53] From its inception, the society prioritized practical demonstrations, with early meetings featuring trials such as investigations into magnetism, capillary action, and the properties of gases using instruments like Boyle's air pump, as documented in the original journal books commencing in December 1660.^[54] These activities exemplified a commitment to first-principles reasoning, dissecting natural processes via hypothesis-testing and measurement, in contrast to the era's lingering reliance on qualitative anecdotes or providential explanations under the interregnum's governance.^[42] By institutionalizing such practices under royal patronage, the society catalyzed a paradigm where scientific legitimacy derived from empirical rigor, influencing subsequent advancements in physics, biology, and chemistry.^[53]

Other Innovations and Publications

In February 1660, John Milton published The Ready and Easy Way to Establish a Free Commonwealth, his final major tract defending republican governance against the mounting momentum for monarchical restoration.^[55] Written amid General George Monck's arrival in London and the readmission of secluded royalist members to Parliament, the work urged a perpetuation of the Commonwealth through a representative council, emphasizing self-governance rooted in civic virtue over hereditary rule.^[40] Despite its logical appeals to historical precedents of failed monarchies and the inefficiencies of popular assemblies, the pamphlet failed to sway events, as Charles II's return later that spring rendered such arguments moot.^[40] The political shift enabled by the Restoration relaxed prior Puritan-era constraints on expression, fostering a broader range of intellectual outputs that affirmed legitimacy of the returned monarchy, though specific technological or antiquarian advancements datable precisely to 1660 remain undocumented beyond ongoing antiquarian inquiries like those of John Aubrey, whose surveys of prehistoric sites laid groundwork for later empirical studies of British monuments.^[56] This freer milieu contrasted with the Commonwealth's doctrinal suppressions, allowing causal exploration of governance and history without immediate fear of prosecution, presaging expanded scientific discourse in subsequent years.

Significance and Legacy

Political Restoration and Stability

The Restoration of Charles II in May 1660 concluded the Interregnum (1649–1660), an era of republican governance marked by repeated failures to achieve stable rule. The Barebones Parliament, convened in July 1653 as a handpicked assembly of Puritan reformers, collapsed within five months amid ideological rifts and legislative paralysis, exemplifying the impracticality of such utopian experiments.^[57] This period's chronic instability, exacerbated by the collapse of the Protectorate after Oliver Cromwell's death in 1658, gave way to monarchical restoration, yielding relative political order that endured without civil war until the Glorious Revolution of 1688.^[58] Charles II's Declaration of Breda, proclaimed on April 4/14, 1660, outlined concessions including general amnesty for civil war participants, provisional liberty of conscience pending parliamentary settlement, equitable resolution of sequestered lands, and full arrears payment to the army to ensure peaceful reintegration.^[39] Implementation proved selective, as the Cavalier Parliament—elected in 1661 with a strong royalist and Anglican majority—eschewed broad toleration in favor of reasserting ecclesiastical uniformity. The Clarendon Code, enacted between 1661 and 1665, imposed strict limits: the Corporation Act (1661) barred nonconformists from municipal offices unless they received Anglican sacraments; the Act of Uniformity (1662) mandated subscription to the Book of Common Prayer for clergy, ejecting about 2,000 Puritan ministers; subsequent Five Mile Act (1665) and Conventicle Act (1664) restricted dissenting assemblies and preaching, explicitly excluding Catholics and Quakers from exemptions and prioritizing pragmatic suppression of factionalism over promised pluralism.^[59][60] These measures underpinned economic recovery by curtailing disruptive religious divisions, fostering a unified framework for mercantile expansion. English overseas trade burgeoned post-1660, with the Navigation Acts enforced more rigorously and new ventures like the Royal African Company's charter (1660) driving commerce; customs revenues, stagnant during the Interregnum, surged, reflecting revived shipping and colonial exchanges.^[61] Naval reconstruction under Charles II transformed the inherited interregnum fleet into a standing professional force, commissioning shipbuilding programs that supported the Second Anglo-Dutch War (1665–1667) and acquisitions such as New Amsterdam (renamed New York) in 1664, thereby securing trade routes and territorial gains.^[62][63] This pragmatic restoration of causal hierarchies—favoring enforceable monarchy over republican idealism—correlated with sustained growth until late-century strains.^[58]

Criticisms and Alternative Perspectives

Puritans and Fifth Monarchists, who had anticipated a more rigorously godly commonwealth, decried the Restoration court's libertine excesses as a relapse into moral corruption, exemplified by Charles II's numerous mistresses and the broader cultural shift toward hedonism following years of austere republican governance.^[64][65] This critique persisted among radicals, culminating in the Fifth Monarchists' armed uprising led by Thomas Venner in January 1661, which aimed to overthrow the monarchy in favor of Christ's direct rule and resulted in the execution of several participants.^[66] Republican holdouts, including surviving regicides and sympathizers, maintained justifications for Charles I's execution by portraying it as a necessary response to perceived tyrannical overreach, though many went underground after 1660 to evade prosecution under the Act of Indemnity and Oblivion, which explicitly targeted the king's judges.^[67] These views framed the Restoration not as a triumph but as a betrayal of revolutionary principles, yet empirical evidence of the prior regime's instabilities—such as the military dictatorship under Cromwell's Major-Generals from 1655 to 1657, which imposed regional governance through armed oversight and suppressed dissent—undermined claims of sustainable republican virtue.^[68] The Commonwealth's record included documented religious persecutions, notably Cromwell's forces massacring approximately 3,500 soldiers and civilians at Drogheda in 1649 during the Irish campaign, justified by military necessity but reflective of broader intolerance toward Catholics and nonconformists despite nominal toleration policies.^[69] Economic disruptions from prolonged civil wars and the Interregnum further eroded support, with trade interruptions in London and a decline in mint output to levels unseen since the early 16th century, contrasting with the Restoration's stabilization.^[70][71] Contemporary accounts indicate widespread public endorsement of the monarchy's return, evidenced by vast crowds greeting Charles II at Dover on May 25, 1660, with tumultuous cheers and salutes, followed by similar acclaim during his London entry on May 29 amid decorations and festivities.^[72][73] Modern narratives occasionally romanticize Cromwell's era as a progressive alternative, but such interpretations overlook the regime's coercive elements and fail to account for the popular repudiation reflected in these receptions, prioritizing instead verifiable outcomes of instability over ideological aspirations.^[74]

Deaths

The executions of regicides following the Restoration marked a pivotal reckoning with the republican past, with ten individuals convicted and put to death in October for their roles in Charles I's trial and execution eleven years prior. Major-General Thomas Harrison, a prominent military leader under Oliver Cromwell and one of the 59 signatories to the king's death warrant, was the first to be hanged, drawn, and quartered on 13 October at [Charing Cross](/page/Charing Cross). John Carew, a Puritan MP who had voted for the regicide, met the same fate on 15 October at [Charing Cross](/page/Charing Cross), as recorded by diarist Samuel Pepys who witnessed the event and noted the crowd's reaction. On 17 October at Tyburn, four more—Thomas Scot (a key prosecutor at Charles I's trial), Adrian Scroop, Gregory Clement, and John Jones—were hanged, drawn, and quartered, their deaths underscoring the new regime's intent to purge remnants of the interregnum without broader reprisals against former parliamentarians. These executions, limited to active participants rather than passive enablers, reflected Charles II's policy of selective justice amid efforts at national reconciliation, though they fueled ongoing royalist sentiment against the "king-killers." Beyond political casualties, 1660 saw losses in intellectual and cultural spheres. Dutch mathematician Frans van Schooten, known for editing and promoting René Descartes' geometric works including the 1659-1661 Geometria that influenced Christiaan Huygens and Gottfried Leibniz, died on 29 May in Leiden at age 45, depriving European science of a key conduit for analytic geometry. Statesman and poet Jacob Cats, Grand Pensionary of Holland and author of emblematic moral works like Sinne- en Minnebeelden (1618) that shaped Dutch literature and ethics, succumbed on 12 September near The Hague at age 82, his passing coinciding with the year's diplomatic shifts in the Dutch Republic. Dutch painter Govert Flinck, a pupil of Rembrandt whose style blended classical themes with baroque portraiture, died on 2 February in Amsterdam, representing a diminishment in the artistic vitality of the Golden Age. These deaths, amid the broader transition to monarchical stability, highlighted the era's undercurrents of continuity in non-political domains despite the upheaval in England.
