Kingdom of England unity ever since. During the reign of Æthelred the Unready (978–1016), a new wave of Danish invasions was orchestrated by Sweyn I of Denmark, culminating after a quarter-century of warfare in the Danish conquest of England in 1013. But Sweyn died on 2 February 1014, and Æthelred was restored to the throne. In 1015, Sweyn's son Cnut the Great (commonly known as Canute) launched a new invasion. The ensuing war ended with an agreement in 1016 between Canute and Æthelred's successor, Edmund Ironside, to divide England between them, but Edmund's death on 30 November of that year left England united
Edward IV of England Edward IV of England Edward IV (28 April 1442 – 9 April 1483) was the King of England from 4 March 1461 to 3 October 1470, and again from 11 April 1471 until his death. He was the first Yorkist King of England. The first half of his rule was marred by the violence associated with the Wars of the Roses, but he overcame the Lancastrian challenge to the throne at Tewkesbury in 1471 to reign in peace until his sudden death. Before becoming king, he was Duke of York, Earl of March, Earl of Cambridge and Earl of Ulster.
