During the late 1990s, after Chechnya's first war against Russia, Movladi Udugov's status as war hero enabled him to take the post of the breakaway Republic's Security Minister. Between 2006 and 2007, following the death of his predecessor Sheikh Abdul Halim, Umarov became the underground President of Ichkeria of the unrecognized government of the Chechen Republic of Ichkeria, the post that Umarov eventually abolished himself when he renounced and abandoned Chechen nationalism in favour of regional pan-Islamism and jihadist ideology. The political mantle of Chechen nationalist separatism was formally taken over by the self-exiled Akhmed Zakayev, Umarov's former wartime comrade and friend turned political rival. Having quit the position of Chechen separatist leader, Umarov subsequently became the self-proclaimed Emir of the entire North Caucasus region of Russia, declaring it a putative Islamic state of the Caucasus Emirate. In 2010, Umarov abortively resigned from the position and appointed Aslambek Vadalov as the new Emir of the Caucasus Emirate, but soon afterwards issued a statement annulling the previous declaration and stating he would remain in his position and rebel Sharia court ruled in favour of Umarov over the rift, following which most other Russian rebel leaders re-swore allegiance to him.
