John Frederick I of Saxony

As a member of the Wettin dynasty, he ruled Saxony and played a significant role in supporting Martin Luther's ideas, which challenged the Catholic Church. His political efforts helped shape religious and territorial changes in Germany during this period. Despite losing his electoral rights at one point, he remained influential in the religious and political landscape of the Holy Roman Empire. His leadership contributed to the spread of Protestantism and the shaping of modern German state structure.
