How did the roman inquisition start?

The Roman Inquisition began in 1542 as a response to the Protestant Reformation and the perceived threat to Catholic doctrine. Established by Pope Paul III, it aimed to combat heresy and maintain the integrity of the Catholic Church. The Inquisition sought to investigate, prosecute, and punish individuals accused of heretical beliefs or practices, employing a system of trials and interrogation to enforce orthodoxy. This marked a significant effort by the Church to assert its authority and curb the spread of Protestantism in Italy and beyond.
