Leinster about the year 900

The following is a provisional list of the kings of Leinster who ruled the Irish kingdom of Leinster (or Laigin) up to 1632 with the death of Domhnall Spainneach Mac Murrough Caomhanach, the last legitimately inaugurated head of the MacMurrough Kavanagh royal line. Today's province of Leinster is considerably larger than the former kingdom.
