20 November 763: The death of King Domhnall mac Murchadha on this day. King Domhnall mac Murchadha was an interesting character. He had retired into a monastery in the year 740 but was active again by 742. He went back into monastic life in 744 but at the same time remained as King of Tara, which he had taken for himself after winning at Seireadh Magh. The most likely explanation is that he became both the Abbot of a great monastery (Clonard?) and King of Tara simultaneously to allow him to exercise control in both civil and religious affairs within his kingdom. It seems to have worked because when he died in 763 he was still the holder of both offices.
