The group was founded in 1974 as the Committee for a Workers' International, by supporters of Militant from 12 countries.[1] In August 2019, a faction left and formed a separate organisation called the "refounded CWI". After initially calling themselves the "CWI Majority", the remaining group renamed themselves International Socialist Alternative in February 2020. The ISA has groups in 30 countries.
