Constantine sent many provisions to the Franks, when they were besieging Antioch. The Armenians were happy to get such powerful allies against their enemies, the Greeks. Alexius could not be very well pleased with the creation of an Armenian Margrave by the Latins, of whom he extorted “an oath of homage and fidelity, and a solemn promise that they would either restore, or hold the Asiatic conquests, as the humble and loyal vassals of the Roman empire”—(Gibbon, iv., 131. London, 1826, published by Jones.) The Armenians translate Margrave by Asbed, that is, Chief of the cavalry.
