Muhlberg was a decisive imperial military victory, but it was not a lasting religious settlement for the Empire as a whole. Continued Protestant resistance, including a later revolt by Maurice of Saxony himself against the very emperor he had helped defeat John Frederick for, forced Charles V to negotiate rather than impose terms outright across all of Protestant Germany, and the war's underlying religious question, Lutheranism's legal standing within the Empire, remained unresolved by the battlefield result alone at Muhlberg.
The Schmalkaldic League had existed specifically to defend the princes and free cities that had adopted the Augsburg Confession against imperial and papal pressure to reverse the Reformation by force of arms, and Charles pursued the war explicitly to restore Catholic religious unity across the whole of the Empire he ruled. That underlying dispute was finally settled not by Muhlberg but by the 1555 Peace of Augsburg, which legally established Lutheranism's standing within the Empire alongside Catholicism, on the enduring principle that each territory's own ruler determined its religion.
