Alaska

Alaska (/əˈlæskə/ ^ⓘ ə-LASS-kə) is a non-contiguous U.S. state on the northwest extremity of North America. Part of the Western United States region, it is one of the two non-contiguous U.S. states, alongside Hawaii. Alaska is considered to be the northernmost, westernmost, and easternmost (the Aleutian Islands cross the 180th meridian into the eastern hemisphere) state in the United States. It borders the Canadian territory of Yukon and the province of British Columbia to the east. It shares a western maritime border, in the Bering Strait, with Russia's Chukotka Autonomous Okrug. The Chukchi and Beaufort Seas of the Arctic Ocean lie to the north, and the Pacific Ocean lies to the south. It is a semi-exclave of the U.S., and is the largest exclave in the world.

Alaska is the largest U.S. state by area, comprising more total area than the following three largest states of Texas, California, and Montana combined, and is the seventh-largest subnational division in the world. It is the third-least populous and most sparsely populated U.S. state. With a population of 740,133 in 2024, it is the most populous territory in North America located mostly north of the 60th parallel, with more than quadruple the combined populations of Northern Canada and Greenland. Alaska contains the four largest cities in the United States by area, including the state capital of Juneau. Alaska's most populous city is Anchorage, and approximately half of Alaska's residents live within its metropolitan area.

Indigenous people have lived in Alaska for thousands of years, and it is widely believed that the region served as the entry point for the initial settlement of North America by way of the Bering land bridge. The Russian Empire was the first to actively colonize the area beginning in the 18th century, eventually establishing Russian America, which spanned most of the current state and promoted and maintained a native Alaskan Creole population. The expense and logistical difficulty of maintaining this distant possession prompted its sale to the U.S. in 1867 for US$7.2 million, equivalent to $162 million in 2024. The area went through several administrative changes before becoming organized as a territory on May 11, 1912. It was admitted as the 49th state of the U.S. on January 3, 1959.

An abundance of natural resources—including commercial fishing and the extraction of natural gas and oil—has enabled Alaska to have one of the highest per capita incomes in the United States, despite having one of the smallest state economies. U.S. Armed Forces bases and tourism also contribute to the economy; more than half of Alaska is federally-owned land containing national forests, national parks, and wildlife refuges. It is among the most irreligious states and one of the first to legalize recreational marijuana. The Indigenous population of Alaska is proportionally the second highest of any U.S. state, at over 15 percent, after only Hawaii.

The name "Alaska" (Russian: Аля́ска, romanized: Aljáska) was introduced during the Russian colonial period when it was used to refer to the Alaska Peninsula. It was derived from an Aleut-language idiom, alaxsxaq, meaning "the mainland" or, more literally, "the object towards which the action of the sea is directed".

Numerous Indigenous peoples occupied Alaska for thousands of years before the arrival of European peoples to the area. Linguistic and DNA studies done here have provided evidence for the settlement of North America by way of the Bering land bridge. At the Upward Sun River site in the Tanana Valley in Alaska, remains of a six-week-old infant were found. The baby's DNA showed that she belonged to a population that was genetically separate from other Native groups present elsewhere in the New World at the end of the Pleistocene. Ben Potter, the University of Alaska Fairbanks archaeologist who unearthed the remains at the Upward Sun River site in 2013, named this new group Ancient Beringian.

The Tlingit people developed a society with a matrilineal kinship system of property inheritance and descent in what is present Southeast Alaska, along with parts of British Columbia and the Yukon. Also in Southeast were the Haida, now well known for their unique arts. The Tsimshian people came to Alaska from British Columbia in 1887, when President Grover Cleveland, and later the U.S. Congress, granted them permission to settle on Annette Island and found the town of Metlakatla, Alaska. All three of these peoples, as well as other Indigenous peoples of the Pacific Northwest Coast, experienced smallpox outbreaks from the late 18th through the mid-19th century, with the most devastating epidemics occurring in the 1830s and 1860s, resulting in high fatalities and social disruption.

Some researchers believe the first Russian settlement in Alaska was established in the 17th century. According to this hypothesis, in 1648 several koches of Semyon Dezhnyov's expedition came ashore in Alaska by storm and founded this settlement. This hypothesis is based on the testimony of Chukchi geographer Nikolai Daurkin, who had visited Alaska in 1764–1765 and who had reported on a village on the Kheuveren River, populated by "bearded men" who "pray to the icons". Some modern researchers associate the Kheuveren with the Koyuk River.
