Pierre Trudeau served as Prime Minister of Canada from 1968 to 1979 and again from 1980 to 1984. He believed in a strong centralized federal government and enacted reforms around official languages, abortion, divorce, and homosexuality. However, this alienated Quebec separatists and western provinces who wanted more power decentralized to provincial governments. Tensions rose between federal and provincial powers, foreshadowing future constitutional crises. Joe Clark briefly became Prime Minister in 1979 but his minority government fell after a failed budget vote, allowing Trudeau to return to power in 1980.
