Ireland

Ireland, sometimes known as the Republic of Ireland, was an island on Earth. It shared the island with Northern Ireland, which was a part of the United Kingdom until the least the 33rd century. (DW: The Beast Below)

During the late 10th and early 10th centuries, Ireland was the site of a major power struggle between the Norse King Sitric Silkbeard of Dublin and the Irish-born King Brian Boru of Munster. Following the first Leinster Revolt in 1000, Sitric's power was severely diminshed. In 1006, he lamented that he had become little more than a lapdog to Brian.

The Book of Kells was crucial to this power struggle. Although it was written on the Scottish island on Iona in the 8th century, it is a powerful symbol of Irishness. Sitric was concerned that if Brian gained possession of the book, he would be able to use it to gain control of Dublin and Ireland as a whole. In 1006, he sent one of his warriors, Olaf Eriksson to enlist the Abbey of Kells' chief librarian Brother Bernard's assistance in protecting the book so as to prevent Brian from using it as a pawn to place himself on the throne of Dublin.

Although Sitric's plan to keep the book out of Brian's hands was successful, his position was further destabilised by a second revolt in Leinster several years later and the Battle of Clontarf in 1014. The Eighth Doctor warned Brother Bernard to stay away from Clontarf during that year. (BFA: The Book of Kells)

In September 1649, the Seventh Doctor, Ace and Hex visited the Kingdom of Ireland during Oliver Cromwell's siege of Drogheda and Wexford. (BFA: The Settling)

In the 20th century, humans sometimes mistakenly assumed Gallifrey was a place in Ireland. (DW: The Hand of Fear, DW: Human Nature) Andrew Harper made a similar assumption about Traken. (BFA: Autumn)

Shortly after Miracle Day in 2011, Ireland went bankrupt along with Greece. (TW: End of the Road)
