Battle of Varna, Turkish victory over a largely Hungarian force on November 10, 1444, in what is now Bulgaria, ending the European powers’ efforts to save Constantinople (now Istanbul) from Turkish conquest and enabling the Ottoman Empire to confirm and expand its control over the Balkans. The Christian retaliation against the advance of the Muslim Ottoman Turks came to a disastrous end at Varna, opening the way to the Ottoman conquest of Constantinople.
The Ottomans first entered Europe when the Byzantine Empire was rapidly dissolving, Italian city-states were fighting among each other, and France and England were sidelined by the Hundred Years’ War. The Ottomans, too, were weak initially, after their disastrous defeat at Ankara in 1402 at the hands of the Mongol armies of Tamerlane. But by 1444 Murad II was able to resume Ottoman expansion in Europe. Fearing that the Ottomans would advance farther into central and western Europe, Pope Eugene IV called for a crusade. János Hunyadi, serving Władysław III, king of both Poland and Hungary, at first inflicted some sharp setbacks on the Ottomans before a truce was agreed. The Christians, made up largely of Hungarian forces, made an elaborate plan for a campaign in 1444, in breach of the truce, considered nonbinding by the Christians since it was agreed with an infidel. The Venetian and Papal fleets were to cut the Ottomans off from reinforcement from Anatolia. This would allow a Christian army to destroy their forces in Europe.
The naval blockade failed to materialize, and by the time the crusader army reached Varna, it faced a numerically far superior Ottoman army that extended across a battle front more than 5 miles wide, with heavy cavalry on both flanks and infantry in the middle. At first, the battle seemed to go well for the crusaders, as Hunyadi formed and held a strong defensive line. But as the Ottoman troops fell back in the face of a cavalry charge, King Władysław rejected Hunyadi’s cautious advice and led the bulk of his forces against the Ottoman center in a rash attempt to capture the Sultan. The Sultan’s elite bodyguard repelled the attack and the king was killed, his head displayed on a pike. The crusaders eventually retreated after taking enormous losses.
Following the battle, Poland remained without a king for three years. Unhindered by further major interference from the central European powers, the Turks extended their control over the Greek rulers in the Peloponnese, who had cooperated with the crusaders. With now no threat from the West, the Ottoman Turks proceeded to conquer Constantinople in 1453 and to reabsorb Serbia by 1459. Hunyadi defeated another superior Ottoman force outside Belgrade in 1456, resulting in a long period of uneasy peace between the Ottoman Empire and Hungary, but Varna marked the last concerted campaign to drive the Turks from Europe until the 19th century.
Losses: Christian, heavy casualties of 20,000; Ottoman, minimal of 50,000.
