Ireland was split into many little princedoms and didn't meddle much in the affairs of other European countries, if at all. Quite early, however, the English kings became lords of Dublin and made the area around it the Pale of (English) settlement, and during the second half of the 14th century, quite a few English settled there. In 1400, the island of Ireland was hit by the Black Death, and relatively more English were killed, since they were concentrated in the cities. Generally, there was less English involvement in Ireland ITTL, since England was preoccupied with affairs on the continent, first because they stayed longer in Aquitaine, and second after they inherited Castille-Portugal.
