Umhaill

Umhaill or Umhall (anglicized as Owill or Owel) was a Gaelic territory around Clew Bay in the west of what is now County Mayo, Ireland, comprising the baronies of Burrishoole (Lower Owel) and Murrisk (Upper Owel). By the 12th century, its ruling dynasty were known as the Uí Máille (O'Malleys). Originally an autonomous part of the kingdom of Connacht, it later became one of the vassal territories of the Mac William Íochtar. Umhaill's last and most famous ruler was Grace O'Malley (Gráinne Ní Mháille), nicknamed "the pirate queen". In 1576, during the Tudor conquest of Ireland, she agreed to the surrender and regrant policy, accepting English inheritance law in return for official title deeds to her lands. On her death the lands were inherited by her son Tibbot "na Long". Umhaill had a strong seafaring culture. Important sites associated with it include Carrickkildavnet Castle, Carrickahowley Castle, Granuaile's Castle and Clare Island Abbey.
