The first settlements were build in the 8th century. Later in the 12th and 13th century the names of the settlements were written down in documents. During the times the villages belonged to different owners. Because of the reformation the people of the village of "Dudenhofen" became protestant, but all the others remained catholic. This led to the situation, that the Dudenhofen people married partners from nearby Babenhausen, Dietzenbach and other protestant places but did not have relatives in the catholic Rodgau villages. Around 1830 the settlements had a total population of about 4,000 people. In 1939 the amount of inhabitants was about 11,500. It increased to about 34,000 in 1970 and to about 45,000 at the end of the 2000s.
