 Before AD 1100, the Catholic Church suppressed what they believed to be heresy, usually through a system of ecclesiastical proscription or imprisonment, but without using torture, and seldom resorting to executions.This very profitable Central European Fourth Crusade had prompted the 14th century Renaissance (translated as 'Rebirth') of Italian city-states including the Papal States, on eve of the Protestant Reformation and Counter-Reformation (which established the Roman Inquisition to succeed the Medieval Inquisition).There followed the discovery of the American continent, and consequent dissolution of West Christendom as even a theoretical unitary political body, later resulting in the religious Eighty Years War (1568–1648) and Thirty Years War (1618–1648) between various Protestant and Catholic states of the Holy Roman Empire (and emergence of religiously diverse confessions).
