What terrified the State, employers, and major elements of the British
Trades Union and Labour Movement was that the Dublin strikers were
linked to an armed force of workers, the Citizens' Army. This was alien
to any preceding political or industrial dispute. It was the first time
in Ireland's, and Britain's, history that the main protagonists against
the State were socialists, and indeed armed ones. British intelligence
warned of the dangers of this strike, noting that this was not just an
industrial dispute, and, if left its own devices, could lead to a
Socialist revolution that might spread to the mainland. This fascinating
period saw Sinn Fein, who were vehemently opposed to the strike,
transformed during the unrest from a fringe group to a major party at
the expense of Labour and socialism.
