The 1920 Manitoba general election was held on June 29, 1920 to elect members of the Legislative Assembly of the Province of Manitoba, Canada. The election resulted in a fragmented parliament, with no group holding effective power over the legislature. Norris's Liberals were re-elected. They remained the largest party, but were reduced to a minority government with 21 seats out of 55. This was the first general election in which women could vote and run for office. Edith Rogers was elected in this election, becoming the first woman elected to the Manitoba Legislature. This was also the first election where Single Transferable Voting was used to elect the Winnipeg MLAs, now ten in number. Background Between the previous 1915 election and the 1920 campaign, Manitoba experienced profound social and cultural change. Since the formal introduction of partisan politics in 1888, Manitoba had been dominated by the Liberal and Conservative parties, which governed the province in succession. After World War I, new political groups and interests emerged to threaten the two-party system. The Winnipeg General Strike of 1919 brought labour issues to the forefront of provincial concern, and radicalized many working-class Manitobans. In previous elections, labour and socialist parties were a marginal force; going into the 1920 election, they stood to make significant electoral gains. In the rural constituencies, several candidates ran for office as farmer representatives, or as "people's candidates" opposed to partisan government. Against this backdrop, the governing Liberal Party of Tobias Norris was forced to run a defensive campaign. Supported by the Winnipeg Free Press, the Liberals portrayed themselves as a stabilizing force amid the province's changes. The 1920 election is notable for its use of Single Transferable Voting in the City of Winnipeg. Previously, the city had been divided into three two-member constituencies, each seat elected in a separate First past the post election. Starting in the 1920 election, Winnipeg was a single ten-member constituency, where each voter had one vote. The method of election was the single transferable voting (STV) system of proportional representation. In the world, this was the largest number of legislators elected in any district using STV for many years. Winnipeg would use STV to elect its MLAS until 1952. Outcome The election resulted in a fragmented parliament, with no group holding effective power over the legislature. Norris's Liberals remained the largest party, but were reduced to a minority government with 21 seats
