Bohdan Khmelnytsky

• 1. Introduction

  ›

  Bohdan Khmelnytsky was born in a village near Chyhyryn sometime around 1595, the son of a Registered Cossack who served a Polish magnate's court. By the time he died in the summer of 1657, he had founded a state, shattered the power of the Polish-Lithuanian Commonwealth, delivered Ukraine into Russian protection, and presided over massacres that killed tens of thousands of people. Oliver Cromwell's English contemporaries compared the two men. Ukrainian students welcomed Khmelnytsky into Kyiv as a Moses. Jewish communities across Europe compared him to Haman. Poles called him the Whip of God, a title previously given to Attila of the Huns.

  How does a Ruthenian nobleman, educated at a Jesuit collegium and fluent in Latin, become the most polarizing figure in the history of an entire region? The answer moves through Ottoman prison galleys, a stolen estate, a stolen bride, a dramatic walk-out from a church in Pereiaslav, and a deathbed from which he still conducted diplomacy. What the source material reveals is a man of extraordinary practical intelligence and equally extraordinary violence, whose legacy nations are still arguing about today.

• 2. Captivity and Formation

  ›

  At the battle of Cecora on the 17th of September 1620, Khmelnytsky's father was killed, and Khmelnytsky himself was captured by the Turks. He was taken to Constantinople as a prisoner of an Ottoman Kapudan Pasha, believed to be Parlak Mustafa Pasha. Some accounts say he rowed as an oarsman in the Ottoman Navy on galleys, which is where he picked up a working knowledge of Turkic languages. He spent the next two years in captivity before returning to Ukraine, either by escape or ransom.

  The ransom question has never been fully resolved. One candidate is Krzysztof Zbaraski, the Commonwealth's ambassador to the Ottomans, who in 1622 paid 30,000 thalers to free prisoners captured at Cecora. Back in Subotiv, Khmelnytsky took over his late father's estate and became a Registered Cossack in the Chyhyryn Regiment. There is a darker footnote from the Ottoman captivity that his political enemies later weaponized: the historian Mustafa Naima recorded that Khmelnytsky either secretly converted to Islam or at least seriously contemplated it. During a meeting with Crimean Khan Islam III Giray, he reportedly performed namaz to prove allegiance to the Muslim faith. Modern historians tend to read this as political theatre, a move in the game of threatening Warsaw and Moscow with the prospect of a Cossack-Ottoman union. Paul of Aleppo, the Syrian traveller who met him in 1654, described a man of devout Orthodox Christian practice.

• 3. The Czaplinski Affair

  ›

  Upon the death of magnate Stanislaw Koniecpolski in March 1646, his successor Aleksander redrew the maps of his possessions and laid claim to Khmelnytsky's estate at Subotiv. Every letter and appeal Khmelnytsky sent to Polish crown representatives went unanswered. At the end of 1645, the Chyhyryn starosta Daniel Czaplinski received official authority from Koniecpolski to seize the property.

  In the summer of 1646, Khmelnytsky secured an audience with King Wladyslaw IV, who gave him a royal charter protecting his rights to Subotiv. It proved worthless in the face of local magnate power. In April 1647, Czaplinski evicted Khmelnytsky from the land, forcing him to move his large family to a relative's house in Chyhyryn. That same year, Motrona, the woman Khmelnytsky planned to marry, was abducted and forcibly wed to Czaplinski during a raid on the estate. A second royal audience that May produced nothing. Khmelnytsky's eldest son Yuriy had already been badly beaten in one of the raids.

  What followed was a winter of travel throughout Ukraine, regiment by regiment, consulting Cossack leaders. Polish authorities arrested him on suspicion of fomenting revolt. The Chyhyryn Cossack polkovnyk who held him was persuaded to let him go. Khmelnytsky headed for the Zaporozhian Sich with a group of supporters. The personal grievance was real, but as even his contemporaries recognized, it was a catalyst for something much larger: oppressed Orthodox Ruthenians had been waiting for a leader.

• 4. Military Victories and State-Building

  ›

  At the end of January 1648, a Cossack Rada unanimously elected Khmelnytsky hetman. He sent letters across Ukraine calling on Cossacks and Orthodox peasants to join the rebellion, fortified Khortytsia, and dispatched emissaries to Crimean Khan Islam III Giray. The Poles took the news lightly at first. They would not do so for long.

  On the 16th of May 1648, Khmelnytsky's forces, aided by the Tatars of Tugay Bey, crushed the Commonwealth army at Zhovti Vody. Ten days later, the 26th of May 1648, the Battle of Korsuń ended in the same outcome. The Patriarch of Jerusalem, Paiseus, visiting Kiev during this period, referred to Khmelnytsky as the Prince of Rus. In February 1649, during negotiations with a Polish delegation led by Senator Adam Kysil, Khmelnytsky declared himself "the sole autocrat of Rus" with power stretching as far as Lviv, Kholm, and Halych.

  State-building followed the military victories. Khmelnytsky made the Zaporozhian Host the supreme authority in the new Ukrainian state and unified military, administrative, financial, economic, and cultural spheres under his command. A new generation of leaders emerged from the Cossack ranks: Ivan Vyhovsky, Pavlo Teteria, Ivan Bohun, Danylo Nechai and Ivan Nechai, and Hryhoriy Hulyanytsky. That same elite would later be instrumental in the period known as the Ruin, eventually undoing much of what the Khmelnytsky era had built.

• 5. Massacres and Their Scale

  ›

  Between 1648 and 1649, Cossacks under Khmelnytsky's command massacred tens of thousands of Poles and Jews, with many more handed to his Crimean Tatar allies as yasir, which is to say as slaves. The massacres continued under his rule at least until 1652, and the aim, according to the source, was the eradication of non-Orthodox Ruthenian populations. The death toll may have reached hundreds of thousands.

  For Jewish communities, the destruction was a historical rupture. Estimates of Jewish deaths from the uprising range from 18,000 to 100,000, including deaths from starvation and disease. Atrocity accounts spread throughout Europe: massacre victims buried alive, cut to pieces, or forced to kill one another. The trauma fed religious movements, contributing to the revival of ideas associated with Isaac Luria and the identification of Sabbatai Zevi as the Messiah. Historian Orest Subtelny wrote that the Khmelnytsky uprising is considered to this day one of the most traumatic events in Jewish history.

  The Tatar alliance had a specific price. In 1649 alone, Crimean Tatars plundered up to 70 Ukrainian towns and hundreds of villages, taking as many as 40,000 inhabitants as slaves. In 1653, the scale was even larger: the khan received permission to take 100,000 captives in exchange for peace with Polish authorities. Contemporary witnesses reported that members of the Cossack starshyna directly oversaw the slave-taking, acting on the hetman's orders. Folk songs from Khmelnytsky's native region of Cherkasy, gathered in the 19th century by Panteleimon Kulish, cursed him as a facilitator of the enslavement of his own people.

• 6. The Pereiaslav Treaty

  ›

  After the crushing defeat at the battle of Berestechko on the 18th of June 1651, in which the Tatars betrayed Khmelnytsky and held him captive while his forces suffered an estimated 30,000 casualties, the Cossacks were forced to sign the Treaty of Bila Tserkva on terms that favoured the Polish-Lithuanian Commonwealth. Khmelnytsky needed a new protector.

  He approached the Ottoman sultan in 1651, and formal embassies were exchanged. The Turks offered vassalship on the model of their arrangements with Crimea, Moldavia, and Wallachia. The general Cossack population found union with a Muslim monarch unacceptable. The other option was the Tsardom of Russia. Despite Khmelnytsky's appeals invoking shared Orthodox faith, Tsar Alexei Mikhailovich waited. The threat of a Cossack-Ottoman union in 1653 finally forced his hand.

  On the 18th of January 1654, in Pereiaslav, a Cossack Rada concluded the treaty with a Russian embassy led by boyar Vasily Buturlin. What the treaty meant has never been agreed upon: historians have read it as a military alliance, a suzerainty, or an outright incorporation of Ukraine into Russia. The ceremony itself nearly collapsed. When the Russian envoy refused to reciprocate with an oath from the tsar to his subjects, as was customary with Polish kings, Khmelnytsky stormed out of the church and threatened to cancel everything. The Cossacks ultimately rescinded the demand. That single gesture of defiance, and then submission, prefigured two centuries of disputed interpretation.

• 7. The Final Years

  ›

  The 1654 treaty brought Russia into the conflict and drove Khmelnytsky's former Tatar allies to the Polish side, initiating new raids that depopulated whole areas of the Sich. By 1656, Sweden had occupied a share of Lithuania, Transylvania's George II Rakoczi had entered the war at Charles X of Sweden's request, and the Commonwealth was barely surviving blows from all directions. Russia attacked Sweden in July 1656, meaning Khmelnytsky's ally was now fighting his overlord.

  The tsar concluded a separate peace with the Poles in Vilnius in 1656. Khmelnytsky's emissaries were not permitted to attend. He wrote the tsar an irate letter accusing him of breaking the Pereiaslav agreement: "The Swedes are an honest people; when they pledge friendship and alliance, they honor their word." He continued conducting diplomacy even when illness had confined him to his bed and forced him to receive the tsar's envoys lying down.

  On the 22nd of July 1657, after an audience with Kyiv Colonel Zhdanovich, Khmelnytsky suffered a cerebral hemorrhage and became paralysed. Less than a week later, at 5 a.m. on the 27th of July 1657, he died. His funeral was held on the 23rd of August, and his body was taken from his capital at Chyhyryn to Subotiv for burial in his ancestral church. In 1664, Polish hetman Stefan Czarniecki recaptured Subotiv, and some Ukrainian historians record that he ordered the bodies of Khmelnytsky and his son Tymish exhumed and desecrated, though other historians dispute this.

• 8. A Contested Legacy

  ›

  Syrian traveller Paul of Aleppo, who met Khmelnytsky in 1654 on the way to Moscow, described a man who refused to be served during banquets, drank from simple cups while his subordinates used silver and gold tableware, drank coffee, smoked tobacco from a pipe, and was known for silent contemplation that could give way to frightening fury. Venetian ambassador Alberto Vimina, visiting Chyhyryn in 1650, described a tall man of sturdy build who personally welcomed any Cossack visitor to his home.

  The man those observers met became, after death, a different figure to each community that inherited him. A monument installed in the centre of Kyiv in 1888, commissioned by Russian nationalist Mikhail Yuzefovich and created by sculptor Mikhail Mikeshin, bore the inscription: "To Bohdan Khmelnytsky from one and indivisible Russia." Its original design had included a vanquished Polish noble, Jewish administrator, and Catholic priest beneath the horse's hooves; Russian authorities found that too xenophobic and removed those figures before installation. The same sculptor placed Khmelnytsky among Russia's prominent figures in the Monument to the Millennium of Russia in Novgorod.

  In a 2018 poll by Ukraine's Rating Sociological Group, 73% of Ukrainian respondents expressed a positive attitude toward Khmelnytsky. He appears on Ukrainian banknotes, a city and region bear his name, and his monument at the centre of Kyiv remains a focal point of the capital. But poet Taras Shevchenko was among his most vocal critics, and the Separate Presidential Brigade protecting Ukraine's president carries his name into a war directly shaped by the choices he made in Pereiaslav in 1654.
