The King of Dublin was the title given to the ruler of the Norse kingdom of Dublin.
Sitric Silkbeard of the Uí Ímair dynasty became the King of Dublin in 989. However, following the first Leinster Revolt in 1000, which was instigated by his great rival Brian Boru, the Irish-born King of Munster, Sitric's position was severely undermined. In 1006, he lamented that he had become little more than a lapdog to Brian. Although he was able to prevent Brian from taking the throne of Dublin by using the Book of Kells, Sitric's control was further destabilised by a second revolt in Leinster and the Battle of Clontarf in 1014.

By the 17th century, Ireland had been unified and its king was Charles I, who also ruled as the monarch of England and Scotland. (PROSE: The Roundheads)
