Since 11 December 2015 the Gülen movement is classified as a terrorist organization by Turkey under the assigned names Gülenist Terror Organisation (Fethullahçı Terör Örgütü, FETÖ) or Parallel State Organisation (Paralel Devlet Yapılanması, PDY). After the failed coup attempt in 2016, the government of Turkey blamed the group for the coup and authorities have arrested thousands of soldiers and judges.[25][26][27] Over ten thousand education staff were suspended and the licenses of over 20,000 teachers working at private institutions were revoked for alleged affiliation to Gülen.[28][29] Fethullah Gülen condemned the coup and denied any involvement.[30][31]
