The naval Battle of Cheshme took place on 5–7 July 1770 during the Russo-Turkish War (1768–1774) near and in Çeşme Bay, in the area between the western tip of Anatolia and the island of Chios, which was the site of a number of past naval battles between the Ottoman Empire and the Republic of Venice. It was a part of the Orlov Revolt of 1770, a precursor to the later Greek War of Independence (1821–1829), and the first of a number of disastrous fleet battles for the Ottomans against Russia. Today it is commemorated as a Day of Military Honour in Russia.

Catherine II, most commonly known as Catherine the Great, was the reigning empress of Russia from 1762 to 1796. She came to power after overthrowing her husband, Peter III. Under her long reign, inspired by the ideas of the Enlightenment, Russia experienced a renaissance of culture and sciences, which led to the founding of many new cities, universities, and theatres, along with a large-scale immigration from the rest of Europe and with the recognition of Russia as one of the great powers of Europe.
