Tom Mann continued to actively champion socialism, communism, and co-operation, until his death in 1941. He published further pamphlets and regularly addressed public meetings, in Britain and abroad. He was arrested for sedition, on several occasions. He continued to be a popular figure in the labour movement, attracting large audiences to rallies and benefits. During the Spanish Civil War, he wanted to fight on the Republican side, but was by that time far too old. A unit of the International Brigade, the Tom Mann Centuria, was named in his honour.
