We learn from the _Book of the Customs of the Empire of Romania_ something about the way in which the feudal system worked in the principality of Achaia. Society was there composed of six main elements—the Prince, the holders of the twelve great baronies, the greater and lesser vassals (among whom were some Greeks), the freemen, and the serfs. The Prince and his twelve peers alone had the power of inflicting capital punishment; but even the Prince could not punish any of the barons without the consent of the greater vassals. If he were taken prisoner in battle, he could call upon his vassals to become hostages in his place, until he had raised the amount of his ransom. No one, except the twelve peers, was allowed to build a castle in Achaia without his permission, and without it any vassal, who left the country and stayed abroad, was liable to lose his fief. Leave of absence was, however, never refused if the vassal wished to claim the succession to a fief abroad, to contract a marriage, or to make a pilgrimage to the Holy Sepulchre, or to the Churches of St Peter and St Paul in Rome or to that of St James at Compostella. But in such cases the vassals must return within two years and two days. The vassals were of two classes, the greater (or _ligii_) and the lesser (or _homines plani homagii_), who took no part in the Council of the Prince. A liege could not sell his fief without the Prince’s consent; but if the liege were a widow—for the Salic Law did not obtain in Frankish Greece, and ladies often held important fiefs—she might marry whom she pleased, except only an enemy of the Prince. When a fief fell vacant, the successor must needs appear to advance his claim within a year and a day if he were in Achaia, within two years and two days if he were abroad. It was the tricky application of this rule which led to the succession of Geoffroy de Villehardouin to the throne of Achaia. Champlitte had been summoned away to claim a fief in France, and had requested his trusted comrade in arms to act as his viceroy till he had sent a relative to take his place. When the news reached the Morea that a young cousin of Champlitte was on his way, Geoffroy resolved to use artifice in order to prevent his arrival in time. He accordingly begged the Doge to assist him, and the latter, who had excellent reasons for remaining on good terms with him, managed to entertain his passing guest at Venice for more than two months. When, at last, young Robert de Champlitte put to sea, the ship’s captain received orders to leave him ashore at Corfù, and it was with difficulty that he managed to obtain a passage from there to the Morea. When he landed there he had, however, a few days still in hand; but the crafty Villehardouin managed by marching rapidly from one place to another to avoid meeting him till the full term prescribed by the feudal pact had expired. He was then informed that he had forfeited the principality, which thus fell
