In 1014 or 1015, Eric Haakonsson leaves Norway and joins Canute the Great for his campaign in England.

The Scandinavian invasion fleet lands at Sandwich in midsummer 1015 where it meets little resistance.

Canute's forces move into Wessex and plunder in Dorset, Wiltshire and Somerset.

Alderman Eadric Streona assembles an English force of 40 ships and submts to Canute.

In early 1016 the Scandinavian army moves over the Thames into Mercia, plundering as it goes.

Prince Edmund attempts to muster an army to resist the invasion but his efforts are not successful and Canute's forces continue unhindered into Northumbria where Uhtred the Bold, earl of Northumbria, is murdered.

The great north English earldom is given by Canute to Eric after he had won control of the north.

After conquering Northumbria, the invading army turns south again towards London.

Before they arrive, King Ethelred the Unready dies (on April 23) and Prince Edmund is chosen king.

Following Ethelred's death, the Scandinavian forces besiege London.

After several battles, Canute and Edmund reach an agreement to divide the kingdom but Edmund dies a few months later.

In 1017, Canute is undisputed king of all England.

He divides the kingdom into four parts; Wessex he keeps for himself, East-Anglia he gives to Thorkell, Northumbria to Eric and Mercia to Eadric.

Later the same year Canute has Eadric executed as a traitor.
