The Conservative Party of Canada has gone by a variety of names over the years since Canadian Confederation. Initially known as the "Liberal-Conservative Party", it dropped "Liberal" from its name in 1873, although many of its candidates continued to use this name.
As a result of World War I and the Conscription Crisis of 1917, the party joined with pro-conscription Liberals to become the "Unionist Party", led by Robert Borden from 1917 to 1920, and then the "National Liberal and Conservative Party" until 1922. It then reverted to "Liberal-Conservative Party"[5] until 1938, when it became simply the "National Conservative Party".[6] It ran in the 1940 election as "National Government" even though it was in opposition.
The party was almost always referred to as simply the "Conservative Party" or Tories.
In 1942, the Tories attempted to broaden their base by electing Manitoba Progressive Premier John Bracken as their new leader at the 1942 leadership convention. Bracken agreed to become the party's leader on the condition that it change its name to the "Progressive Conservative Party of Canada".
