Socialist Party of North America

The Socialist Party of North America was a political party founded in 1911, and the first in North America to adopt the Object and Declaration of Principles of the Socialist Party of Great Britain. The party was formed when the Toronto local of the Socialist Party of Canada seceded in protest over that party's reformism. Its members had been influenced by Moses Baritz, a Socialist Party of Great Britain member resident in Toronto.

The Socialist Party of North America survived for a few years, but failed to grow, and the Party was eventually dissolved. Many of its members rejoined the Socialist Party of Canada.
