Erdogan systematically consolidated his political power by marginalizing potential rivals within the Justice and Development Party (AKP). Friends and allies were abandoned. Political parties that opposed constitutional reform, such as the Peoples’ Democratic Party (HDP), were threatened with legal action. The Turkish Grand National Assembly (TGNA) removed parliamentary immunity of HDP deputies leading to the arrest of 11 party leaders including Co-Chairman Selahattin Demirtas. Erdogan’s consolidation of power and mandatory observance of his ideology had its own name-“Erdoganism.”
