Bilbeis is an ancient fortress city on the eastern edge of the southern Nile delta in Egypt.

This atrocity angered the Coptic Egyptians, who had seen the Crusaders as deliverers but had suffered as much as the Muslim inhabitants of Bilbeis. The Copts ended their support of the Crusaders and united with their non-Christian neighbors against the foreigners
