The Inquisition was an ecclesiastical court and process of the Roman Catholic Church setup for the purpose towards the discovery and punishment of heresy which wielded immense power and brutality in medieval and early modern times. The Inquisitions function was principally assembled to repress all heretics of rights, depriving them of their estate and assets which became subject to the ownership of the Catholic treasury, with each relentlessly sought to destroy anyone who spoke, or even thought differently to the Catholic Church. 
Inquisitions involved terrible cruelty and Torture by the Roman Catholic Church. In the Middle Ages inquisitions were in most of Catholic Europe. After the Reformation there were two well known Inquisitions, the Italian inquisition which threatened Galileo and the Spanish Inquisition. The Spanish Inquisition was overall the worse of the two. There were also inquisitions in some other Roman Catholic Countries.
