Spanish Jewish philosopher (d. 1412). Crescas, communal leader of the Aragonian Jewish communities, was one of the most influential personalities of Spanish Jewry, in particular in his efforts to prevent Jews from being lured away from Judaism in the wake of Christian persecution. His own son was killed during a persecution in 1391. Crescas devoted much of his effort to defending Judaism against theological attacks by Christians and to offering a critique of the popular philosophical trends. His work in Spanish (later translated into Hebrew), Refutation of the Principal Dogmas of the Christian Religion, came to occupy a prominent place in Jewish–Christian polemic.
