Ward became Prime Minister on 6 August 1906, following Seddon's death two months earlier. In his first period of government, Ward advocated greater unity within the British Empire, led New Zealand to Dominion status, and increased New Zealand's contribution to the Royal Navy. His government faced strong opposition from the Reform Party and the newly formed socialist parties. He led the Liberal Party to two election victories, in 1908 and 1911, albeit with a one-seat majority in the latter. He resigned as head of government on 28 March 1912.
