The Battle of Mühlberg took place near Mühlberg in the Electorate of Saxony in 1547, during the Schmalkaldic War. The Catholic princes of the Holy Roman Empire led by the Holy Roman Emperor Charles V decisively defeated the Lutheran Schmalkaldic League of Protestant princes under the command of Elector John Frederick I of Saxony and Landgrave Philip I of Hesse. (named after the town of Schmalkalden in Thuringia where the pact was stipulated), a militarily defensive alliance with a markedly anti-Habsburg and anti-Catholic stance.

Although the birth of a Protestant coalition inside the Empire imperilled his power, Charles V did not initially attack the League. The League meanwhile received support from several free cities (Bremen, Hamburg, Lübeck, Ulm and Strasbourg), wishing to affirm their independence from the central power. The Protestant princes could also count on the support of the Kingdom of France, Charles' main foreign enemy. In need of the military support of the German states in his war against the Ottoman Turks in the eastern regions of his lands, the Emperor chose not to oppose the League and to grant wide autonomy to it. The Protestant leaders were therefore left free to support the Reformation and to fight the power of the Catholic bishops in the lands they controlled.

The conditions that forced Charles V to accept the actions of the League changed after a few years. In 1544 the signing of the Treaty of Crépy ended after decades the conflicts between the Emperor and Francis I of France for the control of the Italian peninsula. After the treaty the League lost the support of the French. Martin Luther's death in 1546 and the temporary cessation of the Turkish threat from the east also put Charles in the best possible condition to focus on the internal enemy that endangered the religious and territorial unity of Imperial Germany.

The opportunity to begin the conflict was given by the rivalry between the elector of Saxony John Frederick I and his cousin Maurice, both belonging to the House of Wettin. Despite his Protestant faith, Maurice had in 1542 refused to join the Schmalkaldic League. In 1546, with the assistance of Ferdinand I, the younger brother of Charles V, Maurice invaded the territory of John Frederick. When the attack begun John Frederick's armies were in Württemberg, but they managed to move to the occupied lands and repel Maurice's forces.

The Emperor decided to take advantage of the divisions between the Protestant armies, and he joined the war in 1547. He occupied Ulm and Württemberg and defeated the Palatine Elector, forcing him to surrender and to leave the League. With the beginning of spring Charles then marched toward Saxony to help Maurice's army and to end his clash with John Frederick, the last Protestant prince still opposing him.

Charles was suffering from gout at that time and his army had to face the desertion of the Papal soldiers that had helped him in the first part of the campaign. In addition the Saxon Elector's army was larger than Charles' forces. However, hoping to encourage a Protestant and anti-imperial uprising in Bohemia, John Frederick took the decision to split his forces and he deployed a large portion of his troops there.

He had also left some small detachments to protect the most vulnerable Saxon cities in order to prevent the entry of Charles' army from the south. With the intention of reaching the well-defended stronghold of Wittenberg, the Elector then marched northwards, abandoning his position in Meissen and camping at the end of April at the town of Mühlberg, leaving only a few troops as guards on the bank of the Elbe river, that he considered too wide to be easily crossed by the imperial forces.

At the head of his army, Charles V arrived at the Elbe on the evening of 23 April. Despite the contrary opinion of his generals, he decided to attack the enemy forces, resting just a few miles away. At dawn on 24 April the first avant-gardes of the imperial army advanced, looking for a way for all the army to cross the river. Helped by the surprise and by the dense fog that had risen from the river, small groups of Spanish and Italian veteran soldiers managed to swim across the river and eliminate the few Saxon troops that were guarding the other side.

Meanwhile, some troops of the tercios of Lombardy and Naples, that were the most experienced soldiers in Charles' army, followed a plan set by Don Fernando Álvarez de Toledo, Duke of Alba and commander-in-chief of the Imperial troops in Germany they managed to spot a ford to use that would allow all the army to cross the Elbe. In addition to this, some veteran soldiers were able to prevent the demolition of a pontoon bridge built by the Saxons, John Frederick had considered an attack from Charles so unlikely that he would have ordered several commanders of his army to go to Mass just when the enemy army was about to complete the crossing of the Elbe. The Saxon forces were completely taken by surprise. As soon as he became aware of the fact, the Elector's first thought was to retreat towards Wittenberg. He soon realized though that his army would be too slow to be prepared to march in a short while; moreover, he was convinced that only a vanguard of the main imperial army was attacking. So he ordered his troops to prepare for battle.

John Frederick chose to deploy his troops along the edge of a forest, in order to prevent a possible encirclement by the imperial cavalry and to have a safer escape route in case of retreat. The emperor Charles V also reached the battlefield and exhorted his troops to fight the Protestants. Due to gout, he was carried to the battle in a litter, rather than mounted in armour on the great warhorse as depicted by his court painter, Titian and assisted to the battle from the rear. The main part of his soldiers were chased and killed or captured.

Some sources report that Emperor Charles V commented on the victory with the sentence Vine, vi y venció Dios (in Spanish "I came, I saw, and God won"), a paraphrase of the famous exclamation pronounced by Julius Caesar.

Aftermath

The battle ended with a complete defeat of the Saxon army which suffered severe losses, estimated at around 2000–3000 men. two years before his death.

The surrender of Philip of Hesse soon afterwards ended the Schmalkaldic War, but the Protestant problem remained unresolved. Many of the princes and key reformers, such as Martin Bucer, fled to England, where they directly influenced the English Reformation. The peace reached between Catholic and Protestants in Germany (Augsburg Interim, 1548) was not enough to bring peace inside the Empire and only in 1555 the Peace of Augsburg stated the end of the wars of religion in the Empire, allowing each ruler to choose between Catholicism and Lutheranism. That principle ended the project to reunite Germany under a single religious confession.

The town of Mühlberg hosts a small museum dedicated to the battle.
