Epochs of the city's history
The Reformation and the Thirty Years' War
Even before Count Philipp von Nassau-Idstein converted to the Protestant faith in 1552, the new doctrine had already established itself in Wiesbaden and the surrounding area.
Count Philipp had already appointed a Protestant pastor to Wiesbaden's St. Mauritius Church in 1543. The Thirty Years' War (1618-1648) also left its devastating mark on Wiesbaden: destruction and depopulation were the consequences, from which the city was slow to recover, and Georg August Samuel Prince of Nassau-Idstein was instrumental in rebuilding the city within its old boundaries.
