The Jewish community in Khaybar, which is north of Medina (formerly Yathrib), flourished in the 7th century. The community of Khaybar aided in rallying an army of 10,000 to "put down [kill] all the Muslims in Medina, men, women and children" in The Battle of the Trench, as relayed by Umar.[1] Midst the siege they sent delegations to the Jewish Muslim allies in Medina and successfully turned them against their Muslim neighbours, breaking the Medina Peace and Mutual Defence Treaty. However that campaign failed, and upon their return to Khaybar, the Muslims retaliated with a counter-campaign of 1,400 soldiers. The outcome did not exceed the death of 93 Jews and 18 Muslims, with 50 injured between parties.[2][3]
