Jan III Sobieski

Sobieski spent more than four decades at war, from the Cossack wars of 1649 to his last Moldavian campaign in 1691. He was badly wounded at Berestechko in 1651, crushed an Ottoman army in its fortified camp at Khotyn in 1673, and as king commanded the relief of Vienna in 1683.²

Family and first campaigns

Sobieski was born on 17 August 1629 at Olesko, the son of Jakub Sobieski, castellan of Kraków. He first fought against the Cossack rising of Bohdan Khmelnytsky, at Zborów in 1649 and at Berestechko in 1651, where he was severely wounded.³

Over the next two decades he fought Cossacks, Tatars, Muscovy, Sweden and the Ottomans. He became grand marshal of the Crown, then field hetman in 1666 and grand hetman, the commander of the Crown army, in 1668.⁴

In October 1667 he held a fortified camp at Podhajce against a larger Tatar and Cossack army, and on 16 October the Tatars made peace with the Commonwealth. The Polish History Museum's calendar gives his army as 10,000 men against twice as many; the Wilanów biography puts him in the camp with 3,000 soldiers.⁵

In a two-day battle ending on 11 November 1673 he attacked Hussein Pasha's Ottoman army in its fortified camp at Khotyn and destroyed it.⁶

Jan III Sobieski's greatest victories

Sobieski's greatest victories were Podhajce in 1667, where he held off a larger Tatar and Cossack army; Khotyn in 1673, where he destroyed an Ottoman army in its fortified camp; Lwów in 1675, against the Tatars; Vienna on 12 September 1683; and the second battle of Parkany on 9 October 1683, won together with imperial troops.⁷

How did Jan III Sobieski become king?

After the death of King Michał Korybut Wiśniowiecki, the nobles met to elect a successor, and the victory at Khotyn made the grand hetman the leading candidate. On 21 May 1674 the election sejm proclaimed Jan Sobieski king. He and his wife, Marie Casimire, were crowned at Wawel in Kraków on 2 February 1676.¹⁵

As king he kept fighting the Ottomans and Tatars. In 1675 he defeated a Tatar army near Lwów, and in 1676 the settlement made with the Ottomans at Żurawno returned part of Ukraine to the Commonwealth but left Podolia in Ottoman hands.¹⁶

Who was Jan Sobieski's wife?

Jan Sobieski's wife was Marie Casimire de la Grange d'Arquien, called Marysieńka in Poland. Born in France in 1641, she grew up at the Polish court of Queen Marie Louise Gonzaga and first married the magnate Jan Zamoyski. After Zamoyski died in April 1665 she married Sobieski, and in 1676 she was crowned queen beside him.¹⁷

They married in secret soon after Zamoyski's death, breaking the custom of a year of mourning, and repeated the wedding in public in July 1665. The date of the secret ceremony is disputed: Kazimierz Waliszewski noted that Sobieski himself gave 6 May, while the Wilanów biography gives 14 May.¹⁸

Their marriage lives on in their letters. They wrote whenever war or travel kept them apart, including his campaigns against the Ottomans in 1675 and 1676 and the march to Vienna in 1683. Both used code names for people and events; Sobieski appears in them as Céladon.¹⁹

The best known of these letters he wrote from the grand vizier's tents on the night of 13 September 1683, the day after the battle, describing the captured camp and its treasures.²⁰

What was Jan III Sobieski famous for?

Jan III Sobieski is famous above all for the relief of Vienna. In 1683 the Ottoman grand vizier Kara Mustafa besieged the Habsburg capital for two months. On 12 September Sobieski, the only crowned ruler among the allied commanders, led the Polish, imperial and German relief army to the victory that lifted the siege.²¹

The road to that battle began with a treaty. On 1 April 1683 Sobieski and Emperor Leopold I agreed to help each other against the Ottomans, and when the Ottoman army reached Vienna on 14 July the Commonwealth mobilized. Sobieski marched by way of Kraków, joined the imperial and German forces by the Danube at the start of September and took the supreme command.²²

Fighting began early on 12 September, as the allied left came down from the ridges of the Wienerwald toward the Danube. The Polish right wing needed most of the day to work through the wooded valleys. In the afternoon Polish hussars attacked; after a general assault the Ottoman army broke, the Poles entered Kara Mustafa's camp, and by evening Vienna was free.²³

On 13 September Sobieski wrote to Pope Innocent XI with a play on Caesar's words: "We came, we saw, God conquered" (Venimus, vidimus, Deus vicit). John Stoye adds that popular acclaim still treated Sobieski as God's instrument. The larger part of the Ottoman army escaped, but Stoye calls the battle one of the most resounding of all Christian victories and Ottoman defeats.²⁴

The winged hussars

Sobieski's attack at Vienna is remembered above all for the Polish winged hussars, the Commonwealth's hussar cavalry. The two main accounts used here differ in detail: John Stoye describes select troops of volunteer hussars leading the Polish advance, while the Polish History Museum's account has a single hussar banner drawing Ottoman cavalry onto Polish guns before the main charge.²⁵

Did Sobieski ever lose a battle?

Yes. Less than a month after Vienna, at the first battle of Parkany in October 1683, his Polish troops were routed and Sobieski himself was in danger of death or capture. The allies won the second battle there on 9 October, but his campaigns in Moldavia in 1686 and 1691 failed, and Kamieniec Podolski stayed in Ottoman hands.²⁶

The Wilanów biography dates the defeat at Parkany to 7 October. After the second battle the allies crossed the Danube and took Esztergom in Hungary.²⁷

What did Sobieski do after Vienna?

After Vienna, Sobieski kept fighting the Ottomans. In March 1684 the Holy League was concluded at Linz, joining Venice to the alliance of king and emperor. He tried to win Moldavia and Wallachia without success, and in 1686 the Commonwealth made the Eternal Peace with Russia, which confirmed the Andrusovo settlement of 1667.²⁸

Kamieniec Podolski, lost to the Ottomans in 1672, remained the prize he never won back. A fortified camp at Okopy Świętej Trójcy was built to blockade it: Instytut Polonika dates its foundation, on the king's orders, to 1692, while the Wilanów biography places it in the 1684 campaign. Podolia and Kamieniec returned to the Commonwealth only in 1699, three years after his death.²⁹

When did Jan III Sobieski die?

Jan III Sobieski died at Wilanów, his residence near Warsaw, on 17 June 1696, after years of poor health. His body lay in the Capuchin church in Warsaw for almost four decades. On 15 January 1734 he was buried in Wawel Cathedral in Kraków, together with Queen Marie Casimire and King Augustus II.³⁰

Historians rate him higher as a soldier than as a ruler. The Polish History Museum calls him one of the greatest commanders of his time but a less energetic politician, and the Encyclopedia of Ukraine notes that his attempts to introduce a hereditary monarchy failed against the senate and the diet.³¹
