The 1911 Liverpool General Transport Strike involved dockers, railway workers and sailors, as well people from other trades. It paralysed Liverpool commerce for most of the summer of 1911. It also transformed trade unionism on Merseyside. For the first time, general trade unions were able to establish themselves on a permanent footing and become genuine mass organisations of the working class. The strike was centred on Liverpool, although other action did take place nationally and throughout Merseyside.
