The Disputation of Paris took place in 1240 in the court of the reigning king of France, Louis IX (St. Louis). It followed the work of Nicholas Donin, a Jewish convert to Christianity, who translated the Talmud and pressed 35 charges against it to Pope Gregory IX by quoting a series of blasphemous passages about Jesus, Mary or Christianity. Four rabbis defended the Talmud against Donin's accusations.
