Gülen condemns terrorism, supports communication between people of different religions, and has initiated dialogue with the Vatican and some Jewish organisations. Until 2013 he was an ally of President Recep Tayyip Erdoğan, who later blamed him for the 2016 Turkish coup d'état attempt. He operates a worldwide organisation called the Gülen Movement also known as FETÖ.
