Conservative campus politics can be traced back to the University of Toronto campus club in 1926. However, the national Progressive Conservative Student Federation was not created until 1946. Campus politics gained importance in the 1950s and played a key role in the rise to power of John Diefenbaker and his eventual overthrow (through a Leadership review). Former Canadian Prime Minister Joe Clark got his political start as a "Youth for Diefenbaker". Today, campus clubs are a way of organizing and involving students in the party, but in the 1950s, campus politics were a venue for the political parties to control student politics.
