On May 27, 1960, General Cemal Gürsel led a military coup d'état, removing President Celal Bayar and Prime Minister Menderes, the second of whom was executed. The system returned to civilian control in October 1961. A fractured political system emerged in the wake of the 1960 coup, producing a series of unstable government coalitions in parliament alternating between the Justice Party of Süleyman Demirel on the right and the Republican People's Party of İsmet İnönü and Bülent Ecevit on the left.
