第6回十字軍
After the Sixth Crusade, from 1231 onwards, the forces of Riccardo Filangieri occupied Tyre on behalf of Emperor Frederick II of Hohenstaufen for more than a decade. They were defeated in 1242 by the baronial party and its Venetian allies. Balian of Ibelin, Lord of Beirut, was appointed royal custodian of Tyre on behalf of Queen Alice of Cyprus. In 1246, King Henry I of Cyprus separated Tyre from the royal domain and assigned the Lordship of Tyre to Philip of Montfort.
