The Anglo-Saxons' awareness of their cultural and racial affiliation with their
continental cousins is well attested, as is their interest in the earliest migrations
of their ancestors to the British Isles from the homelands of northern
Europe. The founding figures who led the migrations from Europe across the
North Sea had names which were preserved by oral tradition well into the
Christian period, and the names of these founders of Anglo-Saxon dynasties
entered the historical record when Christian missionaries introduced the technology
of writing among the Anglo-Saxons.
