The Ottoman Freedom Society (Turkish: Osmanlñ Hürriyet Cemiyeti) a political society founded in 1906 by Talat Pasha in Thessaloniki.
In September 1906, the Ottoman Liberty Society was founded in Thessaloniki at the house of Mithat à Âükrü (Bleda) Bey. The initial meeting led to the third Congress where the founding members, primarily army officers, convened. The founders included Bursalñ Tahir, Naki (Yücekök), Edip Servet (Tör), Kazñm Nami (Duru), Mithat à Âükrü (Bleda), ÃÂmer Naci, ðsmail Canbulat, Hakkñ Baha, Mehmed Talat Bey, and Rahmi (Arslan) Bey.
The society's structure was secretive, adopting a cell-type format. Members were inducted in a clandestine ceremony involving an oath with significant emphasis on confidentiality. The structure included a 'Supreme Council' with key figures like ðsmail Canbolat, Talat Bey, and Rahmi Bey. The organization distinguished itself by spreading among both military and civilian statesmen, primarily based in Thessaloniki.
