It emerged on the lower Lahn river in what is today Rhineland-Palatinate. The castle of Nassau was built in 1125, and since 1160 the county was named after the castle. In 1255 Nassau was divided for princes, and Erfurt to Prussia. Dalberg retained the Aschaffenberg area however, and when the Holy Roman Empire finally came to an end in 1806, this became the core of Dalberg's new Grand Duchy of Frankfurt. Since then the Diocese of Mainz has had two cardinals and via various concordats was allowed to retain the medieval tradition of the cathedral chapter electing a successor to the bishop. This practice has all but disappeared in the Roman Catholic Church.
