How was the Socialist Party of America affected by World War 1?

The Socialist Party of America faced significant challenges during World War I, as the war intensified nationalist sentiments and anti-socialist attitudes in the U.S. Many socialists opposed the war, viewing it as an imperialistic conflict, which led to a decline in their influence and membership. The government's crackdown on dissent, exemplified by the Espionage Act of 1917, further marginalized the party and its leaders, contributing to its fragmentation in the post-war period. Ultimately, the war exacerbated divisions within the party and weakened its position in American politics.
