“Whoever for devotion alone, not to gain honor or money, goes to Jerusalem to liberate the Church of God can substitute this journey for all penance.” These were the words spoken by Pope Urban II during the Council of Clermont, these words led to the First Crusade of the 11th century and would inspire future crusades to the east. These crusades led to millions of deaths and the suffering of people throughout the next two centuries. The Crusades were important to the history of Jerusalem and many other places they ventured to. The Christians acted in response to the Islamic Invasions that had happened centuries ago and continued after the Crusades. These Islamic invaders were also quite brutal, but not too much on those just yet as that will be a future topic on this channel. Stick around to find out the tales of the Crusaders throughout the Middle Ages, on a Day in History.
