The presidency in Turkey underwent significant changes in 2018. Previously, the position was largely ceremonial, with executive authority held by the Prime Minister of Turkey. However, constitutional amendments ratified in 2017 eliminated the role of prime minister and granted the president full executive powers. As a result, President Erdogan has been able to exercise extensive authority over the executive branch of the Turkish government.
