Doroshenko, Mykhailo [Dorošenko, Myxajlo], ?–1628. Hetman of the registered Cossacks in 1625–8. In 1616 he became a Cossack colonel, and he participated in Petro Konashevych-Sahaidachny's campaign against Muscovy and in the Battle of Khotyn in 1621. After Marko Zhmailo's Cossack rebellion against Poland failed, Doroshenko was elected hetman and signed the Treaty of Kurukove with the Polish government in 1625. In the following year he led the registered Cossacks against the Zaporozhian Cossacks, who were opposed to the treaty. During Doroshenko's rule six registered regiments were established for the first time. He supported the Crimean khans of the Girei dynasty against the Turkish supporters of the Moldavian murza Cantemir, and campaigned in the Crimea. Doroshenko died during the siege of Kaffa (now Teodosiia) in the Crimea.
