Upper Bavaria consisted of the Rentamt Munich and Rentamt Burghausen. After the founding of the Kingdom of Bavaria the state was totally reorganised and, in 1808, divided into 15 administrative districts (Regierungsbezirke (singular Regierungsbezirk)), in Bavaria called (Kreise (singular Kreis)).
The Upper Palatinate is a landscape with low mountains and numerous ponds and lakes in its lowland regions. By contrast with other regions of Germany it is more rural in character and more sparsely settled. It borders (clockwise from the north) on Upper Franconia, the Czech Republic, Lower Bavaria, Upper Bavaria and Middle Franconia.
