Cerdic, the Saxon Chieftain who founded the Kingdom of Wessex is also considered the virtual founder of the British Monarchy. His earlier genealogy is considered legendary. The only qualification for kingship in early days was descent from Cerdic. Otherwise, fitness to rule was the only other factor taken into consideration. The genealogy prior to Cerdic should be considered a reignal one and not one of blood; as that always borders on legend.
Old Saxony is the original homeland of the Saxons in the northwest corner of modern Germany and roughly corresponds today to the modern German states of Lower Saxony, Westphalia and western Saxony-Anhalt. Old Saxony is the place from which most of the raids and later colonizations of Britain were mounted. The region was called "Old Saxony" by the later descendants of Anglo-Saxon migrants to Britain; their new colonies in Wessex and elsewhere were the "New Saxony" or Seaxna. In Germany the Saxon lands were known simply as "Saxony".
