When military conflicts broke out between the Ottoman Empire and other states, Greeks usually took arms against the Empire, with few exceptions. Prior to the Greek revolution, there had been a number of wars which saw Greeks fight against the Ottomans, such as the Greek participation in the Battle of Lepanto in 1571, the Epirus peasants' revolts of 1600–1601, the Morean War of 1684–1699, and the Russian-instigated Orlov Revolt in 1770, which aimed at breaking up the Ottoman Empire in favor of Russian interests.[page needed] These uprisings were put down by the Ottomans with great bloodshed.
