Turkey (Turkish: Türkiye), known officially as the Republic of Turkey (Türkiye Cumhuriyeti ), is a Eurasian country that stretches across the Anatolian peninsula in southwest Asia and the Balkan region of southeastern Europe. Turkey borders eight countries: Bulgaria to the northwest, Greece to the west, Georgia to the northeast, Armenia, Azerbaijan (the Nakhichevan exclave), and Iran to the east, Iraq and Syria to the southeast. It borders the Mediterranean Sea to the south, the Aegean Sea to the west, and the Black Sea to the north. Turkey also contains the Sea of Marmara, which is used by geographers to mark the border between Europe and Asia, thus making Turkey transcontinental.
Because of its strategic location astride two continents, Turkey's culture has a unique blend of Eastern and Western tradition. A powerful regional presence in the Eurasian landmass with strong cultural and economic influence in the area between the European Union in the west and Central Asia in the east, Russia in the north and the Middle East in the south, Turkey has come to acquire increasing strategic significance.
Turkey, a developed country, is a democratic, secular, unitary, constitutional republic whose political system was established in 1923 under the leadership of Mustafa Kemal Atatürk, following the fall of the Ottoman Empire in the aftermath of World War I. Since then, Turkey has become increasingly integrated with the West while continuing to foster relations with the Eastern world.

Sinop (from Hittite: Sinuwa, in Greek: Σινώπη/Sinope) is a city with a population of 47,000 on İnce Burun (İnceburun, Cape Ince), by its Cape Sinop (Sinop Burnu, Boztepe Cape, Boztepe Burnu ) which is situated on the most northern edge of the Turkish side of Black Sea coast, in the ancient region of Paphlagonia, in modern-day northern Turkey, historically known as Sinope. It is the capital of Sinop Province.
Long used as a Hittite port which appears in Hittite sources as "Sinuwa" (J. Garstang, The Hittite Empire, p. 74), the city proper was re-founded as a Greek colony from the city of Miletus in the 7th century BC (Xenophon, Anabasis 6.1.15; Diodorus Siculus 14.31.2; Strabo 12.545). Sinope flourished as the Black Sea port of a caravan route that led from the upper Euphrates valley (Herodotus 1.72; 2.34), issued its own coinage, founded colonies, and gave its name to a red arsenic sulfate mined in Cappadocia, called "Sinopic red earth" (Miltos Sinôpikê) or sinople. It escaped Persian domination until the early 4th century BC, and in 183 BC it was captured by Pharnaces I and became capital of the kingdom of Pontus. Lucullus conquered Sinope for Rome in 70 BC, and Julius Caesar established a Roman colony there, Colonia Julia Felix, in 47 BC. Mithradates Eupator was born and buried at Sinope, and it was the birthplace of Diogenes, of Diphilus, poet and actor of the New Attic comedy, of the historian Baton, and of the Christian heretic of the 2nd century AD, Marcion.
It remained with the Empire of the East or the Byzantines. It was a part of the Empire of Trebizond from the sacking of Constantinople by the Fourth Crusade in 1204 until the capture of the city by the Seljuk Turks of Rûm in 1214.
After 1261, Sinop became home two successive independent emirates following the fall of the Seljuks: the Pervâne and the Candaroğlu. It was captured by the Ottomans in 1458.
In November 1853, at the start of the Crimean War, in the Battle of Sinop, the Russians, under the command of admiral Nakhimov, destroyed an Ottoman frigate squadron in Sinop, leading Britain and France to declare war on Russia.
