Marine Workers Industrial Union

The Marine Workers Industrial Union (MWIU) was a short-lived union (1930-1935), initiated by the Communist Party of the USA (CPUSA).

History
In 1927, CPUSA member George Mink traveled to the USSR, attended the fourth congress of the Profintern, and returned to the US as the Profintern's representative of a Transport Workers International Committee for Propaganda and Agitation (TWICP&A) to organize maritime workers in the US. Working with William Z. Foster's Trade Union Educational League (TUEL), he established a Marine Workers Progressive League (MWPL) by 1928. During the CPUSA's factional in-fighting 1928-1929 between followers of James P. Cannon, Jay Lovestone, and Foster, Mink laid low. When Joseph Stalin appointed Foster as head of the CPUSA in 1929, Mink continued his efforts with marine workers.

On April 26–27, 1930, a Marine Workers' League of New York (itself organized in 1928 by the Trade Union Unity League or "TUUL") called a convention that created the Marine Workers' Industrial Union of the USA. This national convention followed coastal conventions held during 1928–1930. The convention adopted a constitution, openly supported the USSR, and elected three delegates to attend the fifth world congress of the Red International of Labor Unions or "Profintern" (itself an arm of the Communist International or "Comintern"). The MWIU openly affiliated with TUUL. According to another source, MWIU decided against TUUL and decided instead to affiliate with the Profintern's Red International of Transport Workers via an International Seamen and Harbors Workers Union (ISH), based in Hamburg, Germany.

During the 1934 West Coast waterfront strike, the International Seamen's Union and the Marine Transport Workers (MTW) of the Industrial Workers of the World (IWW) joined the strike.

In 1935, Roy Hudson, a ranking MWIU official, dissolved the union (then, with 14,000 members) without a vote, and the International Seamen's Union of America succeeded to it.
