Roman rule over Spain ended in 400 AD with the endless barbarian invasions. The re-conquest of Spain by the Eastern Empire was almost an accident. The Emperor Justinian had re-conquered North Africa in 534 and was still fighting the long re-conquest of Italy 535 to 554. It is impossible to say whether Justinian in the early years of his reign had formed any definite plan for re-conquering Spain, but we may be sure that it was one of his ambitions. But before he had completed the subjugation of the Ostrogoths he was invited to intervene in Spain. In a nasty dynastic civil war the Visigoth King Athanagild sought the support of the Emperor Justinian, and the Emperor sent a fleet to the southern coasts of Spain. The connection between certain New Mexican families and the Byzantines will be explored. A short film that will trace the history of these people will be shown. We will also discuss which families show the markers that are most identified with this ancient civilization."
