The son of a Danish king, Sweyn 'Forkbeard' began conquering territory in England in 1003, effectively devastating much of southern and midland England. The English nobility became so disillusioned with their existing king, Ethelred 'The Unready', that they acknowledged Sweyn as king in 1013. Sweyn's reign was short, as he died in 1014, but his son Canute the Great soon returned and reclaimed control of England.
