Other aspects of mass participation in the conflict included strikes by organised workers, in opposition to the British presence in Ireland. In Limerick in April 1919, a general strike was called by the Limerick Trades and Labour Council, as a protest against the declaration of a "Special Military Area" under the Defence of the Realm Act, which covered most of Limerick city and a part of the county. Special permits, to be issued by the RIC, would now be required to enter the city. The Trades Council's special Strike Committee controlled the city for fourteen days in an episode that is known as the Limerick Soviet.
