Albert Duke of Prussia

Elected in 1510, Albert led the medieval military order during a time of decline. He faced challenges from Poland and internal dissent, ultimately converting to Lutheranism in 1523. Albert secularized the Teutonic Order's Prussian lands and became the first Duke of Prussia. This marked a significant shift from a religious state to a secular duchy.

A strong supporter of the Protestant Reformation, Albert established Lutheranism as the official religion of Prussia. He played a crucial role in spreading the faith throughout the region. Albert's reign was marked by both triumphs and challenges. He secured Prussian independence but faced conflicts with Poland and internal struggles. His conversion to Lutheranism had a lasting impact on the region's religious landscape.
