Imperial Forces Defeat Protestants at Mühlberg
In the midst of the Schmalkaldic War, the Holy Roman Empire under Emperor Charles V faced a coalition of Protestant princes known as the Schmalkaldic League. Led by Elector John Frederick I of Saxony and Landgrave Philip I of Hesse, the League sought to resist imperial and Catholic authority amid the Reformation's religious divisions. On April 24, 1547, Charles V's forces, including Spanish troops under the Duke of Alba, crossed the Elbe River near Mühlberg in Saxony and launched a surprise attack at dawn. The imperial army routed the Protestant forces in a brief but decisive engagement, capturing both John Frederick and Philip. The victory strengthened Charles V's position temporarily in the Holy Roman Empire.
