Following his returned from exile to Constantinople in 1908, he became one of the founders of the KTTC and later the
SAK. 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. At a meeting on December 8, 1919, in Istanbul with Thomas Beaumont Hohler, Secretary of State to the British High Commissioner
John de Robeck, Abdulkadir explained that the Kurds and Armenians had reached an agreement both in Istanbul and in Paris. He explained that
Damat Ferid Pasha was requesting help to overthrow the government of Grand Vizier
Ali Rıza Pasha, and that he had then promised the Kurds autonomy and a number of other things. He further stated that it was impossible to estimate what
Mustafa Kemal, together with the Azerbaijanis, who were being instigated by
Enver Pasha and
Halil Kut, could achieve, and that Mustafa Kemal was becoming a greater danger every day. When Hohler asked whether the Hürriyet ve İtilaf Fırkası would use force against Mustafa Kemal, he replied in the affirmative. Tom Beaumont Hohler was very impressed by Abdulkadir's determination to establish his own independent state of Kurdistan. 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. He wielded great influence over the Kurdish population of Constantinople, == Death ==
