Where in Germany and France led the way to during the reformation?

During the Reformation, Germany was significantly influenced by Martin Luther, particularly in regions like Saxony and Wittenberg, where he famously nailed his Ninety-Five Theses to the church door in 1517. In France, the Reformation found traction in cities like Geneva and Paris, although it faced strong opposition from the Catholic Church, leading to widespread persecution of Huguenots. These areas became centers for Protestant thought and dissent against Catholicism, shaping the religious landscape of both countries.
