Pamir Khirghiz people constituted one of the Turkish tribes that suffered from the Russian oppression in the course of the conflicts in the Central Asia. These people immigrated to the Small Pamir since the end of the 19th century. The English-Russian competition in the region ended up with the share of Pamir among Afghanistan, Russia and China and the closure of the borders in the year of 1895. Pamir Khirghiz Turks were confined within the region of Small Pamir. The only khan of the last free Khirghiz people was Haci Rahmankul. He was born in Big Pamir in the year of 1913. His father, Capaarkul Khan had established dominion in the entire Pamir region including the section within the lands of todays Tajikistan that was newly dominated by the Tsarist Russia in that period. Khirghiz Turks immigrated to Afghanistani Pamir in the form of 70 tents of Teyit Khirghiz people under the leadership of Capaarkul Khan. There were between 30 and 40 tents of Teyit Khirghiz people who had come to region from the Chinese Pamir before them.
Upon the death of Capaarkul Khan in the year of 1943, Haci Rahmankul who was at the age of 30 was elected as the khan. Rahmankul Khan endeavoured great efforts and succeeded in the recovery of the Khirghiz economy based on stockbreeding that had collapsed before. Therefore, he acquired the affection of the Khirghiz Turks as a beloved leader.
