Turkey is a democratic, secular, unitary, parliamentary republic with a diverse cultural heritage. Turkey is bordered by eight countries: Greece to the west; Bulgaria to the northwest; Georgia to the northeast; Armenia, the Azerbaijani exclave of Nakhchivan and Iran to the east; and Iraq and Syria to the south. The Aegean Sea is to the west, the Black Sea to the north, and the Mediterranean Sea to the south. The Bosphorus, the Sea of Marmara, and the Dardanelles, which together form the Turkish Straits, divide Thrace and Anatolia; they also separate Europe and Asia.

The current holder of the position is Binali Yldrm of the Justice and Development Party (AKP), who took office on 24 May 2016. - The President of the Republic of Turkey is the head of state of the Republic of Turkey. The Presidency is largely a ceremonial office but has some important functions. In this capacity, the President represents the Republic of Turkey, and the unity of the Turkish nation, as well as ensuring the implementation of the Constitution of Turkey and the organized and harmonious functioning of the organs of state. The articles from 101 to 106 of the Constitution establish all the requirements, election, duties, and responsibilities for the office of the President. The office of the President of Turkey was established with the proclamation of the Republic of Turkey on October 29, 1923. The President of Turkey is often informally referred to as the Cumhurbakan, meaning 'President of the People'.

There are a number of variations of parliamentary republics. Most have a clear differentiation between the head of government and the head of state, with the head of government holding real power, much like constitutional monarchies. Some have combined the roles of head of state and head of government, much like presidential systems, but with a dependency upon parliamentary power. - General elections were held in Turkey on 5 June 1977 . Elections took place in the middle of a political race between the right wing party AP and the left wing party CHP . With the charismatic leadership of Bulent Ecevit , CHP managed to beat one of the symbol figures of the conservative politics of Turkey , Suleyman Demirel . Voter turnout was 72.4 % . CHP 's victory was the zenith of the left wing votes in the history of the Republic of Turkey but still there were no capable partners for CHP to join forces to form the government since the rest of the parliament consisted of right wing parties which were not eager to form a coalition with Bulent Ecevit . Finally , CHP could n't gain a vote of confidence . They would have to wait until 1978 to gain support from some independents and small parties to become the head of the government . CHP could n't keep power for long and soon government control passed on to AP even as the rumblings of the military coup were beginning to be felt .
