Cyrptojudaism and the Spanish Inquisition explores Spanish secret Judaism and the Inquisition, which strove to uproot the "Judaizing heresy" among baptized Jews and their descendants. Even in the 18th-century, Cryptojudaism was still prevalent, but the Inquisition finally triumphed. This book describes the private lives of the cyrpto-Jew, as revealed in their confessions, together with their fate in prison and at the auto defeat at which they abjured their Judaism and were reconciled to the Church or, if not, burnt at the stake.
