Newfoundland was a colony until 1907 and a British dominion from 1907 to 1949. The dominion was situated in northeastern North America along the Atlantic coast and comprised the island of Newfoundland and Labrador on the continental mainland. Before attaining dominion status, Newfoundland was a British colony, self-governing from 1855.
Newfoundland was one of the original "dominions" within the meaning of the Statute of Westminster of 1931 and accordingly enjoyed a constitutional status equivalent to the other dominions at the time. In 1934, Newfoundland became the only dominion to give up its self-governing status, ending 79 years of self-government.
