The Orlov revolt was a Greek uprising that broke out in 1770. It was centered in the Peloponnese, southern Greece as well as in parts of Central Greece, Thessaly and on Crete. The revolt broke out at February 1770 following the arrival of Russian Admiral Alexei Orlov, commander of the Imperial Russian Navy during the Russo-Turkish War (1768–1774), at the Mani Peninsula. It became a major precursor to the Greek War of Independence (which erupted in 1821), was part of Catherine the Great's so-called "Greek Plan" and was eventually suppressed by the Ottomans.
