International Socialist Alternative
International Socialist Alternative is an international association of Trotskyist political parties.
ISA was founded by sections on one side of a split in the Committee for a Workers' International.
History
In 2018 and 2019, a dispute within the Committee for a Workers' International developed around the questions of socialism and identity politics.One group founded the “In Defence of a Working Class and Trotskyist CWI” faction, which considers itself a continuance of the original CWI, using the same name.
A second group, in support of the majority of the CWI's International Executive Committee, later renamed itself International Socialist Alternative and also considers itself the continuance of the original CWI.
Rosa International
Rosa International is an international socialist feminist campaign named after Rosa Luxemburg and Rosa Parks aims to build the socialist-feminist wing of the Labour movement. 25 November is the International Day for the Elimination of Violence against Women, which Rosa marked in 2021 with demonstrations in at least two cities.
