Irish War of Independence 1919-1921

[1919] A Republican guerrilla insurrection began with the declaration of independence of the Irish Republic (January 21, 1919), which was not accepted by the British government or Irish Protestants and their military arm, the Ulster Volunteers. Eamon De Valera was the first president of the Irish Republic.

[1921] A cease-fire in Ireland (July 11) led to a peace agreement that established the north-south partition of Ireland into the Irish Free State and Northern Ireland.

Armed Conflict Events Database

Armed Conflict Events Data (ACED) is an research project providing independent information about known wars, international disputes, civil wars, rebellions, coups, revolutions, genocides and other violent conflicts. ACED has been online since December 2000. Various partial revisions and modifications have been implemented since then, however, the limitations of the this format hamper further development. During 2005, the decision was made to radically restructure the available conflict information into a database. The new Armed Conflict Events Database (ACEDb) will substantially increase the utility of available conflict data for students of military history. As well, it will offer expanded opportunities to add and edit records of conflict. Existing research material will be maintained in its present form but no revisions are planned. More news about the development of ACEDb may be found at News About the Armed Conflict Events Database. Feedback is welcome.
