The siege of Xerigordos in 1096 pitted 6,000 Germans of the People's Crusade under Rainald of Broyes against the Turks commanded by Elchanes, general of Kilij Arslan, the Seljuk Sultan of Rûm. The Crusader raiding party captured the Turkish fort of Xerigordos, about four days' march from Nicaea, in an attempt to set up a pillaging outpost. Elchanes arrived three days later and besieged the Crusaders. The defenders had no water supply, and after eight days of siege, they surrendered on September 29. Some of the Crusaders converted to Islam, while others who refused were killed.

The Battle of Civetot was fought between the forces of the People's Crusade and of the Seljuk Turks of Anatolia on 21 October 1096. The battle brought an end to the People's Crusade; some of the survivors joined the First Crusade.
