Fethullah Gülen, an influential Islamic cleric and former ally turned adversary of Turkish President Recep Tayyip Erdoğan, has died at the age of 83 in the United States. Gülen, accused by Erdoğan of orchestrating the 2016 coup attempt in Turkey, consistently denied involvement in the failed coup. Following the coup attempt, Erdoğan labeled Gülen's movement as a terrorist organization, leading to a significant crackdown on his followers in Turkey. Gülen had lived in self-imposed exile in Pennsylvania since 1999, with Turkey repeatedly seeking his extradition from the U.S. Turkish Foreign Minister Hakan Fidan confirmed Gülen's death and vowed to continue the fight against terrorism, describing Gülen as the leader of a 'dark organisation.' Despite the allegations, Gülen's impact extended internationally, with his movement establishing a vast network of schools and businesses across several continents.
