In the year 1443, some of the Corsicans offered the supremacy to Pope Eugene IV., in the hope that the Church might perhaps be able to restrain faction, and restore peace. The Pope sent his plenipotentiary with troops; but this only increased the embroilment. The people assembled themselves to a diet in Morosaglia, and chose a brave and able man, Mariano da Gaggio, as their Lieutenant-general. Mariano first directed his efforts successfully against the degenerate Caporali, expelled them from their castles, destroyed many of these, and declared their office abolished. The Caporali, on their side, called the Genoese Adorno into the island. The people now placed themselves anew under the protection of the Pope; and as the Fregosi had meanwhile gained the upper hand in Genoa, and Nicholas V., a Genoese Pope, favoured them, he put the government of Corsica into the hands of Ludovico Campo Fregoso in the year 1449. In vain the people rose in insurrection under Mariano. To increase the already boundless confusion, Jacob Imbisora, an Arragonese viceroy, appeared, demanding subjection in the name of Arragon. The despairing people assembled again to a diet at Lago Benedetto, and adopted the fatal resolution of placing themselves under the Bank of St. George of Genoa. This society had been founded in the year 1346 by a company of capitalists, who lent the Republic money, and farmed certain portions of the public revenue as guarantee for its repayment. At the request of the Corsicans, the Genoese Republic ceded the island to this Bank, and the Fregosi renounced their claims, receiving a sum of money in compensation. The Company of St. George, under the supremacy of the Senate, entered upon the territory thus acquired in the year 1453, as upon an estate from which they were to draw the highest returns possible. But years elapsed before the Bank succeeded in establishing its authority in the island. The seigniors beyond the mountains, in league with Arragon, made a desperate resistance. The governors of the Bank acted with reckless severity; many heads fell; various nobles went into exile, and collected around Tomasin Fregoso, a man of a restless disposition, whose remembrance of his family's claims upon Corsica had been greatly quickened, since his uncle Lodovico had become Doge. He came, accompanied by the exiles, routed the forces of the Bank, and put himself in possession of a large portion of the island, after the people had proclaimed him Count.
