This article is the Electoral history of Brian Mulroney, the eighteenth Prime Minister of Canada. A conservative, he served one term as Prime Minister (1984-1993). He led the Progressive Conservative Party of Canada in two general elections, winning back to back majority governments (1984) and (1988). He was the first Conservative prime minister to do so since Prime Minister Sir John A. Macdonald, in 1887 and 1891. Mulroney defeated Joe Clark for the leadership of the Progressive Conservatives in 1983, and then defeated Prime Minister John Turner in the 1984 election. Mulroney's majority in the House of Commons was the largest in Canadian history, passing the record set by John Diefenbaker in 1958. He again led the Progressive Conservatives to the polls in the 1988 general election and was returned to power, but with a reduced majority. Mulroney stood for election to the House of Commons three times, once in a by-election after he was elected party leader, and twice in general elections. He was elected each time, with substantial majorities. Mulroney announced his retirement from politics in 1993 and was succeeded as prime minister and leader of the Progressive Conservatives by Kim Campbell. Summary Mulroney ranks seventh out of twenty-three prime ministers for time in office, serving one term of eight years, 281 days. He was the fifth of eight prime ministers from Quebec, the others being Sir John Abbott, Sir Wilfrid Laurier, Louis St. Laurent, Pierre Trudeau, Jean Chrétien, Paul Martin and Justin Trudeau. Mulroney was involved in politics from a young age, being active in the Progressive Conservative party while in university. Although he did not run for office, he was well-established within the party. In 1976 he ran for the leadership, but came in third, behind Joe Clark and Claude Wagner. However, Clark was defeated in the 1980 general election and triggered a leadership convention in 1983. Mulroney again contested the leadership, and this time defeated Clark. Entering the House of Commons by a by-election in 1983, Mulroney was the Leader of the Opposition until the general election of 1984. He led the Progressive Conservatives to a landslide, winning 211 of the 282 seats, the largest seat total in Canadian history. He again led the party in the 1988 general election and was returned to power, albeit with a reduced majority. Mulroney stood for election to the House of Commons three times, once in a by-election
