When the Frankish Carolingian Empire broke up in 888, Wiesbaden was in the eastern half, called East Francia (which would evolve into the Holy Roman Empire). The town was part of Franconia, the heartland of East Francia. In the 1170s, the Count of Nassau, Walram I, received the area around Wiesbaden as a fiefdom. When Franconia fragmented in the early 13th century, Nassau emerged as an independent state as part of the Holy Roman Empire.
