James Larkin (28 January 1874 – 30 January 1947), sometimes known as Jim Larkin or Big Jim, was an Irish republican, socialist and trade union leader. He was one of the founders of the Irish Labour Party along with James Connolly and William O'Brien, and later the founder of the Irish Worker League (a communist party which was recognised by the Comintern as the Irish section of the world communist movement), as well as the Irish Transport and General Workers' Union (ITGWU) and the Workers' Union of Ireland (the two unions later merged to become SIPTU, Ireland's largest trade union). Along with Connolly and Jack White, he was also a founder of the Irish Citizen Army (ICA; a paramilitary group which was integral to both the Dublin lock-out and the Easter Rising). Larkin was a leading figure in the Syndicalist movement. Larkin was born to Irish parents in Toxteth, Liverpool, England. Growing up in poverty, he received little formal education and began working in a variety of jobs while still a child. He became a full-time trade union organiser in 1905. Larkin moved to Belfast in 1907, where he was involved in trade unionism and syndicalist strike action including organising the 1907 Belfast Dock strike. Larkin later moved south and organised workers in Dublin, Cork and Waterford, with considerable success. He founded the Irish Transport and General Workers' Union after his expulsion from the National Union of Dock Labourers for his taking part in strike action in Dublin against union instructions, this new union would quickly replace the NUDL in Ireland. He later moved to Dublin which would become the headquarters of his union and the focus of his union activity, as well as where the Irish Labour Party would be formed. He is perhaps best known for his role in organising the 1913 strike that led to the Dublin lock-out. The lock-out was an industrial dispute over workers pay and conditions as well as their right to organise, and received world-wide attention and coverage. It has been described as the "coming of age of the Irish trade union movement". The Irish Citizen Army was formed during the lock-out to protect striking workers from police violence. Not long after the lockout Larkin assumed direct command of the ICA, beginning the process of its reform into a revolutionary paramilitary organisation by arming them with Mauser rifles bought from Germany by the
