Askerî was of Circassian descent and co founder of the Teşkilât-ı Mahsusa (Special Organisation), a group involved in guerrilla warfare.

[3] Süleyman Askerî was born to General Vehbi Pasha, who served as military staff at Edirne in 1898 and then in Anatolia,[4] in 1884 in Prizren.

During the days he stayed in Monastir, he joined the Committee of Union and Progress and he married Fadime Hanım, who was an aristocrat of Filibe (present-day Plovdiv).

According to Philip Hendrick Stoddard, he was a brother-in-law of Mehmed Nuri (Conker),[6] who was the oldest friend of Mustafa Kemal (Atatürk).
