Karakol society

The Karakol society (Turkish: Karakol Cemiyeti), also known as the Black Arm, Sentinel Association, or Guard Society, was a Turkish clandestine intelligence organization that fought on the side of the Turkish National Movement during the Turkish War of Independence. Formed in November 1918, it refused to merge itself with Association for the Defense of the Rights of Anatolia and Rumelia under Mustafa Kemal Atatürk. Its leadership was decapitated in the aftermath of the 1920 Turkish Grand National Assembly election, leading to its eventual dissolution in 1926.
