Convicted of heresy, Count Raimond VII died in 1249 without an heir; the county passed to the King of France, and the Capitouls' power weakened. In 1321, the Jews of Toulouse were victims of a massacre during the Shepherds' Crusade, during which homes in the Jewish Quarter were ransacked and those who refused to be baptized were killed. In 1323, the Consistori del Gay Saber was established in Toulouse to preserve the lyric art of the troubadours. Toulouse was the centre of Occitan literary culture for the next hundred years, and the Consistori existed until 1484. The city grew richer, active in the trade of Bordeaux wine, cereals and textiles with England. In addition to the inquisition, plague, fire, flood and the Hundred Years' War decimated Toulouse. Despite immigration the city's population declined by 10,000 in 70 years, and Toulouse had a population of 22,000 in 1405.
