Crusades
The Crusades, the subsequent wars in the name of religion which swept Europe for hundreds of years, involved tens of thousands of people in continuous bloodshed. Nonetheless, with the Crusades came a vital cultural exchange.
Toward the end of this period, in 1215, English barons forced King John to sign the famous Magna Carta. This historic document, a formal recognition of the rights of others, was built on the belief that the basic nature of man was good, not evil, and that he was capable of determining his own destiny.
The provisions included the guaranteed freedom of the church, respect for the customs of towns, protection of the rights of subjects and communities, and what would later be interpreted as a guarantee of the right of trial by jury. These represented the triumph of law over king, and thus reason over force.
Inquisition
But the late fifteenth century ushered in the Inquisition, which again sought to quell mans sense of reason and his reach for spiritual enlightenment. Those subscribing to beliefs unacceptable to the Catholic church were tried and tortured until they renounced their heretical views.
Anyone thought to have strange or different ideas could be labeled a blasphemer or even a witch, then burned at the stake if they refused to accept the established beliefs.
