Henry II, Count of Champagne nephew to both Richard I and Philip II, travelled to Lesser Armenia and managed to persuade Leo that in exchange for Antioch, renouncing its overlordship to Lesser Armenia and to release Bohemond, who in 1201 died. With the death of Bohemond III there followed a 15-year struggle for power of Antioch, between Tripoli and Lesser Armenia. According to the rules of primogeniture Leo's great nephew Raymond-Roupen was the rightful heir of Antioch, and Leo's position was supported by the pope. However, on the other hand, the city commune of Antioch supported Bohemond IV of Antioch, on the grounds that he was the closest blood relative to the last ruling prince, Bohemond III. In 1207 Bohemond IV installed a Greek patriarch in Antioch, despite the East-West Schism, under the help of Aleppo, Bohemond IV drove Leo out of Antioch.
