Joseph Philippe Pierre Yves Elliott Trudeau ( , ; October 18, 1919 – September 28, 2000), also referred to by his initials PET, was a Canadian lawyer and politician who served as the 15th prime minister of Canada from 1968 to 1979 and from 1980 to 1984. He also briefly served as the leader of the Opposition from 1979 to 1980. He served as leader of the Liberal Party of Canada from 1968 to 1984. Trudeau was born and raised in Montreal, Quebec; he rose to prominence as a lawyer, intellectual, and activist in Quebec politics. Although he aligned himself with the social democratic New Democratic Party, he felt that they could not achieve power, and instead joined the Liberal Party. He was elected to the House of Commons in 1965, quickly being appointed as Prime Minister Lester B. Pearson's parliamentary secretary. In 1967, he was appointed as minister of justice and attorney general. As minister, Trudeau embraced social liberalism; his two most notable achievements were decriminalizing homosexual acts and legalizing abortion. Trudeau's outgoing personality and charismatic nature caused a media sensation, inspiring "Trudeaumania", and helped him to win the leadership of the Liberal Party in 1968, when he succeeded Pearson and became prime minister of Canada. From the late 1960s until the mid-1980s, Trudeau's personality dominated the political scene to an extent never before seen in Canadian political life. After his appointment as prime minister, he won the 1968, 1972, and 1974 elections, before narrowly losing in 1979. He won a fourth election victory shortly afterwards, in 1980, and eventually retired from politics shortly before the 1984 election. Trudeau is the most recent prime minister to win four elections (having won three majority governments and one minority government) and to serve two non-consecutive terms. His tenure of 15 years and 164 days makes him Canada's third-longest-serving prime minister, behind John A. Macdonald and William Lyon Mackenzie King. Despite his personal motto, "Reason before passion", Trudeau's personality and policy decisions aroused polarizing reactions throughout Canada during his time in office. While critics accused him of arrogance, of economic mismanagement, and of unduly centralizing Canadian decision-making to the detriment of the culture of Quebec and the economy of the Prairies, admirers praised what they considered to be the force of his intellect and his political acumen that maintained national unity over the Quebec sovereignty movement.
