Michael Joseph Savage, Australian-New Zealand politician, 23rd Prime Minister of New Zealand (b. 1872)

Michael Joseph Savage (23 March 1872 – 27 March 1940) was a New Zealand politician who served as the 23rd prime minister of New Zealand, heading the First Labour Government from 6 December 1935 until his death.

Savage was born in the Colony of Victoria (present-day Australia), and emigrated to New Zealand in 1907. A labourer, he became a trade unionist, and in 1910 was elected president of the Auckland Trades and Labour Council. Savage supported the formation of the New Zealand Labour Party in July 1916. He was active in local politics before his election to the House of Representatives in 1919, as one of eight Labour members returned in that election. Savage was elected unopposed as Labour Party Leader in 1933.

Savage led the Labour Party to its first ever electoral victory in the 1935 election. He won public support for his government's economic recovery policies and social welfare programme. His popularity assured the Labour Party of an even more significant electoral victory in the 1938 election. His government joined Britain in declaring war against Germany in 1939. Savage's health declined rapidly after Labour's second electoral victory and he died in office. He was succeeded as head of government by Peter Fraser.

Savage saw himself as spokesman on behalf of his entire party and worked to keep its multiple factions in harness, although a left-wing critic of his leadership, John A. Lee, was expelled. Commonly known as the architect of the New Zealand welfare state, Savage is generally regarded by academics and the general public as one of New Zealand's greatest and most revered prime ministers. To date he is the only New Zealand prime minister or premier to serve under three monarchs (George V, Edward VIII and George VI).
