Walram I, Count of Nassau, had received the area around Wiesbaden as a fiefdom in the 1170s.
When Franconia fragmented in the early thirteenth century, Nassau had emerged as an independent state as part of the Holy Roman Empire.
Wiesbaden had in 1232 become a reichsstadt, an imperial city, of the Holy Roman Empire I.
However, the Archbishop of Mainz, Siegfried III, orders the city's destruction in 1242 during the war of Emperor Frederick II against the Pope.
