Andronikos I Komnenos
Basil was a member of the Kamateros family, which provided a number of leading officials in the 12th century. He initially served under Manuel I Komnenos (r. 1143–1180) as a diplomat, but after a disastrous mission in Italy, he fell out of favour and was banished. His fortunes revived under Andronikos I Komnenos (r. 1183–1185), who had also been exiled by Manuel.
