"The Song of Dermot and the Earl" is an anonymous Anglo-Norman verse chronicle written in the early 13th century in England. It retells the 1170 invasion of Ireland by Diarmait Mac Murchada, the deposed King of Leinster, and Strongbow in 1170 (the "earl" in the title), the wars that followed between Strongbow and Haskulf Thorgilsson, the last Hiberno-Norse King of Dublin, and Ruaidrí Ua Conchobair, the last High King of Ireland, and the subsequent visit to Ireland by King Henry II of England in 1172.
