Pope Urban II Preaches the First Crusade at Clermont
On November 27, 1095, at the Council of Clermont in France, Pope Urban II delivered the sermon traditionally regarded as launching the First Crusade. He called on Western European nobles and knights to aid Byzantine emperor Alexios I against the Seljuk Turks and to take Jerusalem. Chroniclers describe crowds crying “Deus vult” — “God wills it” — as they took up the cross as a badge of their vow. The call set off a series of armed expeditions that reshaped politics, religion, and trade across the eastern Mediterranean for centuries.
