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; DiodorusSiculus 14.31.2; Strabo12.545). Sinope flourished as the Black Sea port of acaravan 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 sulfatemined in Cappadocia, called "Sinopic red earth" (MiltosSinôpikê) or sinople.
Sinope 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.MithradatesEupator was born and buried at Sinope, and it was the birthplace of Diogenes, ofDiphilus, 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 Eastern Roman Empire 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 to two successive independent emirates following the fall of the Seljuks: the Pervâne and the Jandarids. 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.
Sinop hosted a US military base that was important for intelligence during the cold war era. The US base was closed in 1992.
Explorer Bob Ballard discovered an ancient ship wreck north west of Sinop in the Black Sea and was shown on National
