The Portuguese Inquisition is formally established in Portugal in 1536 at the request of its king, John III.
Manuel I had asked for the installation of the Inquisition in 1515 to fulfill the commitment of marriage with Maria of Aragon, but it is only after his death that Pope Paul III acquiesces.
In the period after the Medieval Inquisition, it is one of three different manifestations of the wider Christian Inquisition along with the Spanish Inquisition and Roman Inquisition.
