Commercial and military interactions with Europeans brought new Western influences to the Cilician Armenian society. Many aspects of Western European life were adopted by the nobility including chivalry, fashions in clothing, and the use of French titles, names, and language. Moreover, the organization of the Cilician society shifted from its traditional system to become closer to Western feudalism. The European Crusaders themselves borrowed know-how, such as elements of Armenian castle-building and church architecture. Cilician Armenia thrived economically, with the port of Ayas serving as a center for East–West trade.
