On This Day: 28th May  Events and documents from this date in history

The Labour Party was founded on the 28th of May 1912 as the political wing of the Irish Trades Union Congress.

The Socialist Party of Ireland was founded in 1949, associated with the Socialist Party of Great Britain and World Socialist Movement.

As stated in the preface to their 1949 manifesto:

On May 28th, 1949, a number of workers, representing Socialist Groups in Dublin and Belfast, met in Belfast and decided that the Groups should coalesce and form the Socialist Party of Ireland. That decision was subsequently ratified by the members of the Dublin and Belfast Groups; and so was born the first political party in Ireland to publicly and unequivocally declare its object to be the establishment of Socialism.
