The Vikings first raided Britain in 787 AD and established settlements after repeated invasions in the 9th century. They conquered large parts of England, establishing the Danelaw and controlled the kingdom until the restoration of the Saxon Wessex dynasty in 1042. The Vikings also invaded and settled in Scotland, Ireland, the Scottish islands, and parts of Wales, though they did not gain control of all of Wales. They were skilled seafarers and craftsmen who founded many settlements throughout Northern Europe before Christianization ended their expansion.
