Yarmuk was founded as a unit of around 30 Balkars and Kabardinians led by Muslim Atayev (Emir Sayfullah), which trained at the Chechen warlord Ruslan Gelayev's camp in Pankisi Gorge, Georgia. In 2002 the group helped Gelayev's forces in a raid of the village of Galashki in the Republic of Ingushetia. Upon their return to Kabardino-Balkaria, Atayev and his men launched a recruitment drive among alienated and radicalized youth. Mounting pressure from a continued crackdown led the group's leader, Mussa Mukozhoyev (Musa Mukozhev), to join the underground. Many local young radicals had joined the Islamic Peacekeeping Army that invaded the republic of Dagestan from Chechnya in 1999 or fought on the Chechen separatist side in the Second Chechen War.
