The first Prime Minister of Canada (1867–1873, 1878–1891) and one of Canada’s Fathers of Confederation. The dominant figure of Canadian Confederation, he had a political career which spanned almost half a century. Macdonald served 19 years as Canadian Prime Minister; only William Lyon Mackenzie King served longer.
Macdonald was born in Scotland; when he was a boy his family immigrated to Kingston, Upper Canada (today in eastern Ontario). He articled with a local lawyer, who died before Macdonald qualified, and Macdonald opened his own practice, although not yet entitled to do so. He was involved in several high-profile cases and quickly became prominent in Kingston, which enabled him to seek and obtain a legislative seat in 1844. He served in the legislature of the colonial Province of Canada and by 1857 had become premier under the colony’s unstable political system.
When in 1864 no party proved capable of governing for long, Macdonald agreed to a proposal from his political rival, George Brown, that the parties unite in a Great Coalition to seek federation and political reform. Macdonald was the leading figure in the subsequent discussions and conferences, which resulted in the British North America Act and the birth of Canada as a nation on 1 July 1867.
Macdonald was designated as the first Prime Minister of the new nation, and served in that capacity for most of the remainder of his life, losing office for five years in the 1870s over the Pacific Scandal (corruption in the financing of the Canadian Pacific Railway). After regaining his position, he saw the railroad through to completion in 1885, a means of transportation and freight conveyance that helped unite Canada as one nation. Macdonald is credited with creating a Canadian Confederation despite many obstacles, and expanding what was a relatively small country to cover the northern half of North America. By the time of his death in 1891, Canada had secured most of the territory it occupies today.
He died 6 June 1891.
