August 17, 1629 – June 17, 1696
Did you know?
After Vienna, he paraphrased Caesar's famous 'veni, vidi, vici' in his letter to the Pope, replacing the last word with 'Deus vicit' — God conquered — the most famous line of the war.
“We came, we saw, God conquered.”
Jan Sobieski was the son of a Ruthenian magnate who rose through the ranks of the Polish-Lithuanian military to become the greatest soldier of his age. Educated at Jagiellonian University in Kraków, he toured Western Europe as a young man and mastered French, Latin, and several other languages. His military career began in the Cossack and Swedish wars, and he distinguished himself so completely against the Ottomans at the Battle of Khotin in 1673 — winning a crushing victory over a far larger Turkish force — that the Polish nobility elected him king the following year. As king, Sobieski was consumed by the Ottoman threat. When the call came from Vienna in 1683, he marched south with the Polish army and took command of the relief force by agreement of the allied princes. On September 12 he led the largest cavalry charge in recorded history — 18,000 horsemen, including 3,000 of his own winged hussars — down the Kahlenberg and into the Ottoman camp. The Turkish army, which had been within days of taking the city, disintegrated. Sobieski entered the grand vizier's abandoned tent, sent the captured Ottoman banners to the Pope, and wrote to his wife: 'All the common people kiss my hands, my feet, my clothes.' His later years were bitter. The Polish nobility refused to fund further campaigns, his sons quarreled over the succession, and the alliance with the Habsburgs — who had not shared the spoils of Vienna — soured. He died in 1696, three years before the Treaty of Karlowitz, having saved Christendom and gotten remarkably little gratitude for it.

c. 1634 – December 25, 1683

After his execution, his skull was reportedly sent to Vienna as a war trophy and displayed in a cabinet of curiosities; a skull claimed to be his is still held by the Wien Museum.
“I shall conquer the city and the world will be mine.”Reported in a later source
Merzifonlu Kara Mustafa Pasha was the adopted son and protégé of the powerful Köprülü family of grand viziers who had restored Ottoman military power in the mid-seventeenth century. He rose through the Ottoman provincial administration and military, eventually succeeding his foster brother Fazıl Ahmed Pasha as Grand Vizier in 1676. Ambitious, capable, and arrogant, he was the driving force behind the decision to besiege Vienna — against the counsel of more cautious advisors who remembered that Suleiman the Magnificent had failed before the same walls in 1529. Kara Mustafa's plan was not unreasonable: the Habsburg Empire was distracted by Louis XIV's aggressions, the Hungarian rebels under Imre Thököly had opened the road, and Vienna's fortifications were outdated. He arrived before the city with perhaps 150,000 men in July 1683 and conducted a methodical siege, driving mines toward the walls rather than risking costly assaults. The strategy might have worked — the walls were breached and the garrison was near collapse — but he fatally underestimated the speed of the relief force and failed to fortify his camp against attack from the Kahlenberg heights. When Sobieski's cavalry swept down the hillside on September 12, the Ottoman army was caught between the garrison and the relief force and shattered. Kara Mustafa retreated to Belgrade, where he was strangled with a silk bowstring on the sultan's order on Christmas Day 1683 — the traditional Ottoman punishment for a grand vizier who failed. His skull was reportedly sent to Vienna as a trophy.

Did you know?
Rejected by Louis XIV as too small and ugly for the French army, he became the general who inflicted France's worst defeats — Blenheim, Turin, and Malplaquet — making the Sun King's refusal the costliest personnel decision in French history.
“Where I am, there shall be the battle.”Reported in a later source
Eugene was born in Paris, the son of an Italian prince and a niece of Cardinal Mazarin. Slight, ugly, and destined by his mother for the Church, he was rejected by Louis XIV for a commission in the French army — reportedly because the Sun King thought him too small for a soldier. It was the worst personnel decision in French military history. Eugene crossed the border, entered Habsburg service, and spent the next fifty years making France regret it. He first saw action at the siege of Vienna in 1683 as a twenty-year-old volunteer and was immediately recognized as exceptional. He rose quickly through the Imperial army, commanding dragoons, then a regiment, then an army. His genius was a combination of audacity in the field and mastery of logistics: he was the rare general who could improvise a devastating attack and also make sure his men were fed. At Zenta in 1697 he caught the Ottoman army crossing the Tisza River and attacked without orders — the result was perhaps the most lopsided victory in European military history, with 25,000 Ottomans killed against 500 Imperial dead. Zenta made him the most famous soldier in Europe, but it was only the beginning. In the War of the Spanish Succession he partnered with Marlborough to win Blenheim, Oudenarde, and Malplaquet, and he went on to fight the Ottomans again in 1716–18, capturing Belgrade. He served three emperors, never married, collected books and art, and built the Belvedere Palace in Vienna. When he died in 1736, even his enemies acknowledged that he had been the greatest general of his age — and possibly any age.

c. 1638 – June 4, 1701
Did you know?
When the Ottoman mines blew a massive breach in the walls on September 4, Starhemberg personally led the counterattack that closed it — the garrison was eight days from collapse when the relief arrived.
“Let the Turks come. We will hold the walls or die on them.”Reported in a later source
Count Starhemberg was an experienced soldier from one of Austria's oldest noble families who had fought in the wars against France and the Hungarian rebels. When Leopold I fled Vienna in July 1683 — taking most of the court and much of the population with him — he left Starhemberg in command of the city with a garrison of roughly 15,000 men and a set of fortifications that were widely considered inadequate against a modern siege. For two months Starhemberg held the city against perhaps ten times his numbers. He organized countermining operations to detect and destroy Ottoman tunnels, led sorties against the siege works, and maintained discipline and morale despite dwindling supplies, growing casualties, and an epidemic of dysentery. When the Ottomans breached the walls in early September, he organized desperate counterattacks that bought the critical days needed for the relief army to arrive. Starhemberg's defence of Vienna was one of the great defensive actions in military history. His garrison suffered over 5,000 dead by the time Sobieski arrived. After the relief, he continued to serve the Empire in various military and political capacities, but nothing in his later career matched those two months. He died in 1701, respected as the man who held Vienna when it mattered most.

June 9, 1640 – May 5, 1705
Did you know?
He was a talented composer who wrote operas, ballet music, and hymns — his court was one of the great musical centers of Europe, and his passion for music was far more genuine than his appetite for war.
“I would rather lose my crown than abandon the Catholic faith.”Reported in a later source
Leopold I was never supposed to be emperor — he was the second son, intended for the Church, and became heir only when his elder brother died of smallpox. He inherited a sprawling, creaking empire and spent his entire reign fighting to hold it together against Louis XIV to the west and the Ottoman Empire to the east. He was devoutly Catholic, personally cautious, and politically shrewd, with a genuine talent for music — he composed operas that were performed at the Viennese court. When Kara Mustafa's army appeared before Vienna in 1683, Leopold fled the capital — a decision that was militarily sensible (the emperor could not risk capture) but politically humiliating. He organized the relief effort from Passau, negotiating the alliance with Sobieski that saved the city. After Vienna, Leopold forged the Holy League with Pope Innocent XI's backing and directed the sixteen-year campaign that drove the Ottomans from Hungary — the greatest territorial expansion in Habsburg history. The irony of Leopold's reign is that the man who fled Vienna won more territory than any Habsburg since Charles V. By the Treaty of Karlowitz in 1699, Austria had absorbed Hungary, Transylvania, and Slavonia, transforming the Habsburg Empire from a primarily German state into a multinational great power. Leopold died in 1705, in the middle of the War of the Spanish Succession, still fighting Louis XIV.

Sultan of the Ottoman Empire

January 2, 1642 – January 6, 1693
Did you know?
Known as 'Mehmed the Hunter,' he was so obsessed with hunting that he reportedly spent more days in the field chasing game than attending to affairs of state — the empire was effectively run by his grand viziers.
The hunt is my domain; the war is the vizier's.Historical paraphrase
Mehmed IV became sultan at the age of six after his father Ibrahim was deposed and strangled. His early reign was dominated by court intrigue and near-collapse — the empire was bankrupt, the provinces were in revolt, and the Venetians were attacking Crete. He was saved by the Köprülü family of grand viziers, who restored order with brutal efficiency and put the Ottoman military machine back in working condition. Mehmed IV's own interests were predominantly in hunting — he was nicknamed 'the Hunter' and spent enormous amounts of time and money on elaborate hunts in Thrace and Anatolia. He delegated the business of war almost entirely to his grand viziers, first the Köprülüs and then Kara Mustafa Pasha. It was Kara Mustafa's ambition, backed by Mehmed's passive assent, that launched the campaign against Vienna in 1683. The catastrophe at Vienna was followed by the loss of Buda, the humiliation at Mohács, and the progressive unraveling of Ottoman control over Hungary. The military mutinied in 1687 after the Second Battle of Mohács and deposed Mehmed, installing his brother Suleiman II. Mehmed spent his remaining years in confinement in the old palace at Edirne, reportedly still obsessed with hunting. He died in 1693, having reigned for thirty-nine years and overseen both the Ottoman Empire's last great expansion and the beginning of its long retreat.

August 24, 1655 – January 4, 1707
Did you know?
His nickname 'Türkenlouis' — 'Turk Louis' — was a mark of such popular affection that it survives in German to this day, and the defensive lines he built in Baden are still called the Türkenlouis Lines.
“The Turks are brave; we must be braver.”Reported in a later source
Louis William of Baden-Baden was the most consistently successful Imperial commander of the Great Turkish War. Born into the margraviate of Baden-Baden, he entered Imperial military service young and fought his first campaign against the Ottomans at the siege of Vienna in 1683, where he commanded an Imperial cavalry regiment. He proved himself so capable that he was given increasingly important commands over the following years. His greatest achievement was the Battle of Slankamen in 1691, where his army met the Ottoman counteroffensive under Grand Vizier Fazıl Mustafa Pasha. The battle was a murderous clash — both armies fought with desperate ferocity for hours — and was decided when a musket ball killed the Grand Vizier. The Ottoman army collapsed, and the counteroffensive was permanently broken. Louis of Baden earned the nickname 'Türkenlouis' from a grateful German public and became a national hero. He went on to serve as commander on the Rhine in the War of the Spanish Succession, where his cautious, methodical style was less suited to the faster-moving campaigns against the French. He built the famous Türkenlouis defensive lines in Baden and died in 1707 at Rastatt, where the palace he built as a victory monument still stands.

Sultan of the Ottoman Empire

February 6, 1664 – December 29, 1703
Did you know?
He was the last Ottoman sultan to personally command an army in battle — his catastrophic defeat at Zenta ensured that no sultan would try it again for over a century.
I will lead the armies of Islam in person, as my ancestors did.Historical paraphrase
Mustafa II came to the Ottoman throne in 1695 determined to reverse the catastrophic losses his predecessors had suffered since Vienna. Unlike his uncle Mehmed IV, who had been content to hunt while his viziers fought, Mustafa declared he would lead the army in person — the first sultan to take the field in decades. He was earnest, devout, and brave, qualities that made him admirable but not necessarily effective against a general like Eugene of Savoy. His first campaign in 1695 produced a genuine victory at Lugos, where his army overran General Veterani's outnumbered force. It was enough to convince Mustafa that his personal leadership could turn the war around. In 1697 he led a larger army into the Balkans, aiming to recapture lost territory in Hungary. On September 11, his army was caught crossing the Tisza River at Zenta by Eugene of Savoy, who attacked without waiting for orders. The result was annihilation — perhaps 30,000 Ottomans killed, the Grand Vizier dead, and Mustafa barely escaped across the river. Zenta ended the war and Mustafa's ambitions. He signed the Treaty of Karlowitz in 1699, ceding Hungary, Transylvania, and Slavonia — the greatest territorial loss in Ottoman history. He was deposed by a palace revolt in 1703 and died the same year, aged thirty-nine, the last Ottoman sultan to lead an army in the field.
