The Progressive Party of Saskatchewan was a provincial section of the Progressive Party of Canada, and was active from the beginning of the 1920s to the mid-1930s. The Progressives were an agrarian social democratic political movement. Dedicated to political and economic reform, the Progressive movement challenged economic policies that favoured the financial and industrial interests in Central Canada over agrarian and, to a lesser extent, labour interests. Like its federal counterpart, it favoured free trade over protectionism. The movement can be considered the first partisan expression of western alienation in Canada.
