what year was considered the beginning of the Inquisition?

Answer 1

The Medieval Inquisition is a term historians use to describe the various inquisitions that started around 1184, including the Episcopal Inquisition (1184-1230s) and later the Papal Inquisition (1230s).

The Spanish Inquisition was set up by King Ferdinand and Queen Isabella of Castile in 1478 with the approval of Pope Sixtus IV.

The Portuguese Inquisition was established in Portugal in 1536 by the King of Portugal, João III, as a Portuguese analogue of the more famous Spanish Inquisition.

Pope Paul III established, in 1542, a permanent congregation staffed with cardinals and other officials, whose task was to maintain and defend the integrity of the faith and to examine and proscribe errors and false doctrines. This body, the Congregation of the Holy Office, now called the Congregation for the Doctrine of the Faith, part of the Roman Curia, became the supervisory body of local Inquisitions.
