List of participants in the Nine Years' War (Ireland)

The war was fought in the late 16th and early 17th century and was a conflict between a coalition of Irish lords and their Spanish allies against the English and their authorities in Ireland.

Beginning with the alliance between Tyrone and Tyrconnell in 1593, most of the Irish kingdoms and lordships gradually assembled, either voluntarily or through coercion, into a loose confederation whose aim was to expunge English rule in Ireland once and for all.

The generous terms offered by Mountjoy to the Irish in the Treaty of Mellifont were quickly undone by his successor, Sir Arthur Chichester.

This was a calculated and deliberate tactic on the part of the Irish, with Essex once quipping to O'Neill "thou carest for religion as much as my horse".

[5] While aid and financial support had been relatively forthcoming during the war years, the decisive defeat at Kinsale coupled with Spain's two failed armadas in 1596 and 1597 made it highly unlikely that they would attempt further landings in Ireland.
