The document discusses the Gülen movement, a religious and social movement in Turkey led by Fethullah Gülen from his home in Pennsylvania. Turkish President Recep Tayyip Erdogan has accused the movement of orchestrating a failed coup attempt against his government. The Gülen movement promotes moderate Sunni Islam and operates schools and organizations around the world. However, some observers believe the movement may want more political power and influence in Turkey. The alliance between Erdogan and Gülen has broken down in recent years due to accusations of corruption investigations targeting Erdogan's government.
