Provisional Sinn Féin
Formed in the 1970 split, Provisional Sinn Féin grew from a marginal force into one of Ireland’s most significant parties, its trajectory running from armed struggle to the peace process and the Good Friday Agreement.
Other Major Republican Organisations
Official Sinn Féin
Official Sinn Féin remained under the existing leadership after the 1970 split, pursuing a Marxist, all-Ireland political strategy that eventually gave rise to the Workers’ Party.
The Irish Republican Socialist Party
Founded in 1974 by Seamus Costello and others who broke from the Officials, combining revolutionary republicanism with Marxist class politics, closely associated with the INLA.
Republican Sinn Féin
Founded in 1986 by those who rejected the abandonment of abstentionism, positioning itself as the legitimate continuation of pre-split Sinn Féin.
The Prison Struggle
One of the most significant chapters in the modern tradition, from the broader prison struggle through the defining crisis of the 1980–81 hunger strikes.
Documents and Ephemera
Booklets, posters, calendars, and miscellaneous material offering a window into the movement’s everyday culture and propaganda beyond its formal publications.
Foreign Support Groups
The Provisional and Official movements’ international networks, from diaspora support groups in Britain to NORAID in America and solidarity campaigns across the European left.
 The British Left and Irish Freedom: Support Groups and Campaigns |  Irish America and the Republican Struggle |  Global Support for Irish Republicanism |
Other Republican groups and publications
A selection of organisations and publications beyond the main parties and paramilitary groups, from youth movements to sovereignty advocacy, spanning the twentieth century and into the twenty-first.
