Newfoundland became a Dominion, like Canada, on September 26th, 1907. The Dominion sent troops to the Great War, sent a delegation to the Paris Peace Conference of 1919, had a High Commissioner to the UK, and was as self-governing as any other Dominion.
Unfortunately, the Great Depression hit the Newfoundland economy very hard, and, combined with a huge war debt, a huge railway debt, and a highly divided and ineffectual political process resulting in most of the country being disillusioned with the effectiveness of democracy, the pressure forced it to ask the UK for help, which was provided on the condition of direct government control by Britain. The Newfoundland legislature voted itself out of existence on February 16th, 1934, after which the country was controlled by a commission serving under the Governor; the only democratic institution left on the island being the city council of St. John’s.
Efforts to restore independence were superseded, first by World War II, then by negotiations to join Canada. Of the ten men to serve as the Prime Minister of Newfoundland, only one survived to see it join Confederation at one minute before midnight on March 31, 1949.
