The Irish Citizen Army
The ICA was created as a workers' defence militia but soon grew into a an revolutionary army of Labour. This a short piece on the organisation from 1913 to 1916.
The Spanish Civil War
These pages represent a few pieces of information about the Irishmen who went to fight on behalf of the Spanish Republic during the Anti-Fascist war, 1936-39. (I need to recommend Ireland and the Spanish Civil War as an excellent source of information for anyone trying to find out more about the subject.)
