This is a list of the evolution of the borders of the United Reich of New Bayern. This lists each change to the internal and external borders of the country, as well as status and name changes. It also shows the surrounding areas that eventually became part of the Reich. Each stage has a map, to show what the specific makeup of the country was at any given time.
Neubayern was originally much smaller than its current area, and was formed after the unification of thirteen independent states to form the Reich. After unification, the Reich expanded eastward, enlarging its borders multiple times, both through peaceful means and annexation. The original thirteen states grew into sixty states and city-states. Many of these were at first independent duchies and kingdoms which were incorporated into the Reich. Some states were also formed through the division of existing ones, or the merger thereof.
