Such were the arrangements between the company and the mother-country, arrangements which worked so well that in 220 years there was only one revolt against her, when Marshal Boucicault occupied Genoa for the King of France. Considering their contract thereby annulled, the Giustiniani deposed the _podestà_ and on December 21, 1408, proclaimed their independence. Venice allowed them to buy provisions and arms; but in June, 1409, a Genoese force under Corrado Doria forced them to yield[494]. Let us now look at their relations with foreign powers. Of these, three were at one time or another a menace to their existence—the Greek Empire, Venice, and the Turks. Both Anne of Savoy[495] and Cantacuzene demanded the restoration of Chios from the Republic, which replied that no official orders had been given for its capture and the government could assume no responsibility for the acts of a private company, nor could it dislodge the latter without great expense; at some future date, however, when circumstances were more favourable, it would undoubtedly be possible to restore it to the Emperor. The latter was not satisfied with this reply, but bade the Genoese envoys, who were sent to pacify him, fix a definite date for the evacuation of Chios. It was then agreed between him and the Republic that the _maonesi_ should retain the city of Chios, and enjoy its revenues, for ten years, on condition that they paid an annual tribute of 12,000 gold pieces to the Emperor, hoisted his flag, mentioned his name in their public prayers, and received their metropolitan from the church of Constantinople. The rest of the island, including the other forts, was to belong to the Emperor, and to be governed by an Imperial official, who was to decide all disputes between the Greeks, while those between a Greek and a Latin were to be referred to the two Byzantine and Genoese authorities sitting together. At the end of the ten years, calculated from Cantacuzene’s occupation of Constantinople, the Genoese were to evacuate Chios altogether. Vignoso and his co-partners, however, declined to be bound by an arrangement made between the Emperor and the Republic, whereupon Cybo attempted to restore Greek rule, and perished in the attempt. The two Foglie were, however, temporarily reoccupied[496], but the Greek peril ceased when the Emperor John V Palaiologos in 1363 granted Chios to Pietro Recanelli and his colleagues in return for an annual payment of 500 _hypérpera_ (or £224)[497]. Eight years earlier the position of the _maona_ had been strengthened by the same Emperor’s gift of Lesbos as his sister’s dowry to another Genoese, Francesco Gattilusio, whose family, as time went on, ruled also over Thasos, Lemnos, Samothrace, Imbros, and the town of Ænos on the mainland, in 1913 the Turkish frontier in Europe. In 1440 John VI renewed the charter of 1363.
