In 1918 Abdulkadir became president of the Society for the Elevation of Kurdistan even though Emin Ali Bedir Khan opposed him. As such, he lobbied for an autonomous Kurdish region before the diplomats of France, Great Britain and the USA in Constantinople. The Peace Conference in Paris was discussed in the conversations. But he opposed that foreign powers were engaged in the creation of a future state in the aftermath of the defeat of the Ottoman Empire. In an interview given to the newspaper Ikdam in February 1920 Abdulkadir declared he was an adherent of an autonomous Kurdish region with a leadership elected by Kurds. He was also supportive of the achievements of Şerif Pasha (who supported an autonomous Kurdistan) at the Peace Conference in Paris. Nevertheless, the Grand vizier Damat Ferid Pasha suspected Abdul-Kadir was organizing Kurdish tribal leaders in Anatolia in preparation for independence. As his objection against a Kurdish independence was made public, the dispute between two leaders of the SAK, namely Abdulkadir and Emin Ali Bedir Khan who favored independence emerged and the SAK was dissolved. According to Robert Olson, the British intelligence reported that by 1924 Ubeydullah was the registered as the head of the Azadî office in Constantinople.
