Socialist Party of America | Workers of the World Unite

Welcome to the Socialist Party of America website Workers of the world, Unite!

The Socialist Party of America (SPA) was a multi-tendency democratic-socialist political party in the United States, formed in 1901 by a merger between the three-year-old Social Democratic Party of America and disaffected elements of the Socialist Labor Party which had split from the main organization in 1899.

In the first decades of the 20th century, it drew significant support from many different groups, including trade unionists, progressive social reformers, populist farmers, and immigrant communities. Its presidential candidate, Eugene V. Debs, twice won over 900,000 votes (in 1912 and 1920), while the party also elected two United States Representatives (Victor L. Berger and Meyer London), dozens of state legislators, more than a hundred mayors, and countless lesser officials. The party's staunch opposition to American involvement in World War I, although welcomed by many, also led to prominent defections, official repression and vigilante persecution. The organization was further shattered by a factional war over how it should respond to the October Revolution in Russia in 1917 and the establishment of the Communist International in 1919.
