The fast approaching Turkish danger ought to have united all the Latin states of the Levant against the common foe, to whom they all eventually succumbed. An attempt at union was made by Pope Gregory XI, at the instance of the Archbishop of Neopatras; and a congress of the Christian rulers of the East was convened by him to meet at Thebes in 1373. We can well imagine how the ancient city, the capital of the Athenian duchy, was enlivened by the arrival of these more or less eminent persons, or their envoys; how the Archbishops of Neopatras and Naxos preached a new crusade against the infidel in the church of Our Lady; how every one applauded their excellent advice; and how personal jealousies marred the results of that, as of every subsequent congress on the Eastern question. Scarcely had the delegates separated, when Nerio Acciajuoli, Baron of Corinth, the boldest and astutest of them all, a worthy scion of that great Florentine family of bankers established for a generation in the principality of Achaia showed his appreciation of the value of unity by seizing Megara as the first step on the way to Athens. It is an interesting proof of the popularity of Catalan rule among those Greeks, at any rate, who held office under the Company, that one of the warmest defenders of Megara was a Greek notary, Demetrios Rendi, who afterwards rose to a position of importance at Athens. Such was the weakness of the once terrible Catalan state that the upstart Florentine’s attack remained unavenged. The fall of Catalan rule was now only a question of time.
