Since 1940, Turkey has frequently been under extraordinary rule, either the whole of the country or specific provinces. According to Articles 119-122 of the 1982 Constitution the four types of extraordinary rule are martial law ("sıkıyönetim"), state of emergency ("olağanüstü hal", OHAL), mobilization ("seferberlik") and situation of war ("savaş hali"). Martial law has been abolished and all other forms have been merged into single form of state of emergency since 2017 amendment to Turkish constitution.
