The first Liberal prime minister of Canada was Alexander Mackenzie, who served from 1873 to 1878.12
He assumed the office following the fall of the Conservative government led by Sir John A. Macdonald. Although Mackenzie was a significant figure in the Liberal Party of Canada, his government faced challenges regarding economic policy and lacked a cohesive parliamentary group, leading to the party's defeat in the 1878 election.13
