The SPNY is currently the state chapter of the Socialist Party USA (SPUSA), an organization which emerged from the ashes of the old SPA in 1973.
A bitter dispute over trade union policy led to a split of the SLP in July 1899, with a dissident faction (disparagingly known as the “Kangaroos”) headed by lawyers Henry L. Slobodin and Morris Hillquit.
On Saturday, June 16, 1900, a joint convention was held in New York City bringing together delegates from the dissident SLP and the Chicago SDP.
A nine-member State Committee was elected that included, among others, German editor Herman Schlueter, Leonard D. Abbott, and future National Secretary of the Springfield SDP William Butscher.
[3] During its height in the 1910s, the party fielded candidates for the office of Mayor,[4] seats in the New York State Assembly and the House of Representatives.
[14] Many former members of the Debs caucus joined David McReynolds in founding the Socialist Party of the United States of America in 1973.
[citation needed] After failing to renew their charter, the Socialist Party of New York City was revived in February 2017.
