Mykhailo Doroshenko (Ukrainian: Михайло Дорошенко; died 1628) was a prominent Ukrainian Cossack military leader and Hetman of the Registered Cossacks of the Polish–Lithuanian Commonwealth from 1622 until his death in 1628. He is remembered for his campaigns against the Ottoman Empire and the Crimean Khanate, and for his efforts to protect the Cossack liberties and the Orthodox faith.
Early Life and Career Little is known about Doroshenko's early life. He rose through the ranks of the Zaporozhian Cossacks, distinguishing himself as a skilled military commander. He participated in various campaigns during the Polish-Muscovite War (1617–1618) and played a significant role in the Battle of Khotyn in 1621, where a combined Polish-Lithuanian and Cossack army decisively defeated an Ottoman invasion.
Hetmanate Elected Hetman in 1622, Doroshenko's tenure was marked by continuous military activity aimed at defending Ukraine's borders from external threats.
- Anti-Tatar and Anti-Ottoman Campaigns: He frequently led Cossack forces against incursions by the Crimean Tatars, who often raided Ukrainian lands for slaves and plunder. He also engaged in naval expeditions (chaika raids) against Ottoman strongholds along the Black Sea coast.
- Relations with Poland: While serving the Polish–Lithuanian Commonwealth, Doroshenko consistently advocated for greater autonomy and recognition for the Registered Cossacks. He sought to maintain a delicate balance, leveraging Cossack military power in the Commonwealth's defense while asserting their distinct identity and rights.
- Diplomacy: Doroshenko engaged in diplomatic efforts, notably attempting to forge an alliance with Muscovy against the Ottoman Empire, a move that often caused tensions with his Polish overlords.
Death and Legacy Mykhailo Doroshenko died in 1628 during a daring campaign. He led a Cossack army, reportedly accompanied by Crimean Murzas opposed to the reigning Khan, in an attempt to liberate the captive Christian population of Kaffa (modern Feodosia) in Crimea, a major Ottoman slave market. He was killed during the siege of the city.
Doroshenko's leadership solidified the Cossack reputation as formidable warriors and protectors of the Ukrainian lands. His efforts to balance service to the Commonwealth with the pursuit of Cossack interests contributed to the evolving political landscape of early modern Ukraine.
