In the following years, due to territorial changes (e. g. loss of Tyrol, addition of the Palatinate), the number of Kreise was reduced to 8. One of these was the Untermainkreis (Lower Main District). In 1837 king Ludwig I of Bavaria renamed the Kreise after historical territorial names and tribes of the area. This also involved some border changes or territorial swaps. Thus the name Untermainkreis changed to Lower Franconia and Aschaffenburg, but the city name was soon dropped, leaving just Lower Franconia.
