Alexander Mackenzie was the second Prime Minister of Canada, serving from 1873 to 1878. He is notable for being the first leader of a political party other than the Conservative Party to hold the office, representing the Liberal Party. His tenure was marked by efforts to promote economic development and infrastructure while facing challenges such as scandals and the fallout from the Pacific Scandal that had tarnished the previous government led by Sir John A. Macdonald.
