the Irish kings in Dublin in November 1171. He also ensured that his moral claim to Ireland, granted by the supposed 1155 papal bull Laudabiliter, was reconfirmed in 1172 by Pope Alexander III, and also by a synod of all the Irish bishops at the Synod of Cashel. He added "Lord of Ireland" to his many other titles. Before he could consolidate his new Lordship he had to go to France to deal with his sons' rebellion in 1173. Ruaidrí Ua Conchobair was soon ousted, first as King of Ireland and eventually as King of Connacht. The Lordship directly controlled a small territory in Ireland surrounding the cities of Dublin and Waterford, while the rest of Ireland was divided between English lords and court curiales. The 1175 Treaty of Windsor, brokered by St Lawrence O'Toole with Henry II, formalised the submission of the Gaelic clans that remained in local control, like the Uí Conchobair who retained Connacht and the Uí Néill who retained most of Ulster. Diarmait's male-line descendants included Art Óg mac Murchadha Caomhánach (d. 1417), who revived the kingship of Leinster, and Cahir mac Art Kavanagh (died 1554) who continued to rule parts of Leinster independently of the English until the Tudor conquest of Ireland in the 16th century. The last proclaimed King of Leinster, Domhnall Spáinneach Mac Murchadha Caomhánach, died in 1632. Later senior descendants who retained the position among the Irish upper-classes included Arthur MacMorrough Kavanagh (1831–1889) and his son, Walter MacMurrough Kavanagh 1856–1922). Dermot McMorrough Kavanagh (d. 1958) was recognised as Chief of the Name of Clann Caomhánach (Kavanagh) in his lifetime. Diarmait died about 1 May 1171 and was buried in Ferns Cathedral, where his grave can be seen in the outside graveyard. Ancestry Theatrical representations In the play The Dreaming of the Bones by W. B. Yeats, the ghosts of Dermot and Derbforgaill rescue an Irish rebel during the Easter Week rebellion, and reveal that they are bound until an Irishman can forgive them for bringing the Normans to Ireland.
