The third was the kingdom of the West Saxons, founded by Cerdic in
419; and contained Cornwall, Devonshire, Dorsetshire, Wiltshire,
Somersetshire, and Hampshire, with the Isle of Wight and Berkshire,
though the remains of the Britons likewise inhabited Cornwall: the
principal places were Winchester, Southampton, Portsmouth,
Salisbury, Dorchester, Sherborne, and Exeter: it continued till the
Norman Conquest, being 547 years, and ended in 1066, having been
governed by 17 monarchs, during the heptarchy, of whom five were
Pagans, and 12 Christians: the last of whom was Egbert, who, in 829,
became sole monarch of England.
