Turkey survived a military coup attempt on July 15 that killed over 240 people and wounded more than a thousand others. Immediately after the putsch, the Justice and Development Party (AK Party) government along with President Recep Tayyip Erdoğan pinned the blame on the Gülen movement.

The movement denies any involvement.

According to a statement from Interior Minister Süleyman Soylu on April 2, a total of 113,260 people have been detained as part of investigations into the Gülen movement since the July 15 coup attempt, while 47,155 were put into pre-trial detention.
