Leinster

Leinster was a Gaelic Irish kingdom whose Kavanagh rulers held a reduced territory in Wexford and the Wicklow Mountains. In 1337 Donald Kavanagh belonged to the family that ruled from its traditional seat at Ferns.

Art MacMurrough-Kavanagh ruled from 1375 to 1417 and tied down King Richard II during his Irish expeditions of 1394 and 1395. The Tudors absorbed the lordship in the sixteenth century, leaving Leinster as a province under English administration.
