Alaska is a state in the United States of America, in the northwest of the North American continent. It is the largest U.S. state by area (by a substantial margin), and one of the wealthiest (per capita) and most racially diverse.
The area that became Alaska was purchased from the Russian Empire on March 30, 1867, for 7.2 million dollars (at 2 cents per acre). The land went through several administrative changes before becoming an organized territory on May 11, 1912 and the 49th state of the U.S. on January 3, 1959. The name “Alaska” was already introduced in the Russian colonial time, when it was only used for the peninsula and is derived from the Aleut alaxsxaq, meaning “the mainland,” or more literally, “the object towards which the action of the sea is directed.” It is also known as Alyeska, the “great land”, an Aleut word derived from the same root.
Alaska is one of two U.S. states not bordered by another state, Hawaii being the other. Alaska has more coastline than all the other U.S. states combined.[5] It is the only non-contiguous U.S. state on continental North America; about 500 miles (800 km) of Canadian territory separate Alaska from Washington State. Alaska is thus an exclave of the United States, part of the continental U.S. but is not part of the contiguous U.S.[6] Juneau, Alaska’s capital city, though located on the mainland of the North American continent, is inaccessible by land—no roads connect Juneau to the rest of the North American highway system.
The state is bordered by Yukon Territory and British Columbia, Canada, to the east, the Gulf of Alaska and the Pacific Ocean to the south, the Bering Sea, Bering Strait, and Chukchi Sea to the west and the Beaufort Sea and the Arctic Ocean to the north.
Alaska is the largest state in the United States in land area at 570,380 square miles (1,477,277 km²), more than twice as large as Texas, the next largest state. It is larger than all but 18 sovereign nations.
