The focus of the Spanish Inquisition in the late 15th century primarily revolved around religious uniformity and the persecution of heresy, especially targeting converted Jews (conversos) and Muslims (moriscos). Established in 1478 under Ferdinand and Isabella, the Inquisition sought to ensure that those who had converted to Christianity did so sincerely. Suspected heretics faced trials that often led to severe punishments, including imprisonment and execution. The Inquisition played a significant role in consolidating Catholic orthodoxy in Spain, influencing social and political structures as it created a climate of fear and suspicion. It left a complicated legacy intertwined with issues of faith and identity in Spanish history.
