Alaska is the largest U.S. state, over twice the size of Texas, four times the size of California, and a fifth the size of the whole of continental United States. It joined the U.S. in 1959 to become the 49th state, just seven months before Hawaii joined.
In 1867 it was bought by the U.S. from the Russians, costing seven million dollars. Oil is its primary source of revenue, thanks to its expansive oil and natural gas reserves. Alaska is fiscally stable (and relatively isolated from the rest of the U.S.’s financial crises), making it a sensible choice for business start-ups.
