Ergenekon is the name given to an alleged clandestine, Kemalist ultra-nationalist organization in Turkey which, according to an instructor at the Police Academy in Ankara, most likely has ties to members of the country's military and security forces. The would-be group, named after Ergenekon, a mythical place located in the inaccessible valleys of the Altay Mountains, is accused of terrorism in Turkey.
Ergenekon is by some believed to be part of the "deep state." The existence of the "deep state" was affirmed in Turkish opinion after the Susurluk scandal in 1996. Alleged members have been indicted on charges of plotting to foment unrest, among other things by assassinating intellectuals, politicians, judges, military staff, and religious leaders, with the ultimate goal of toppling the incumbent government.
By April 2011, over 500 people had been taken into custody and nearly 300 formally charged with membership of what prosecutors described as "the Ergenekon terrorist organization," which they claimed had been responsible for virtually every act of political violence – and controlled every terrorist group – in Turkey over the last 30 years
