EDMONTON — Alberta's next provincial election has been called for May 29. The Conservatives held power in the province for more than 40 years before an upset in 2015 led to changes in the political landscape.

Here's a look at Alberta elections over the past two decades:

Progressive Conservatives, 2004

The PC party, in power since 1971, returns to government under Ralph Klein. Klein, who has been premier since 1992, resigns after a leadership review in 2006. Ed Stelmach becomes party leader and premier.

Progressive Conservatives, 2008

The PCs are elected under Stelmach. In 2011, Stelmach announces he is not seeking re-election and the party votes in Alison Redford as leader and premier.

Progressive Conservatives, 2012

The party wins under Redford. The Liberals, who have been the official Opposition since 1993, are replaced by the Wildrose Alliance Party. In 2014, Redford steps down after declining support and a controversy over spending. She is replaced by Dave Hancock on an interim basis. Former federal Conservative cabinet minister Jim Prentice then becomes leader and premier. Wildrose leader Danielle Smith crosses the floor with eight other party members to join the PCs.

Alberta New Democratic Party, 2015

The NDP under Rachel Notley forms government for the first time in Alberta history. The Wildrose Party continues as the Opposition and the PCs are relegated to third place. Prentice resigns on election night. In 2017, the Wildrose and the PCs join to form the United Conservative Party. Former Conservative cabinet minister Jason Kenney is voted in as UCP leader.

United Conservative Party, 2019

The UCP is elected and the NDP forms the Opposition. In 2022, after a dismal leadership vote, Kenney announces he's stepping aside and Smith replaces him as leader and premier.
