Geographically, the Palatinate was divided between two small territorial clusters: the Rhenish, or Lower, Palatinate and the Upper Palatinate. The Rhenish Palatinate included lands on both sides of the middle Rhine River between its Main and Neckar tributaries. Its capital until the 18th century was Heidelberg. The Upper Palatinate was located in northern Bavaria, on both sides of the Naab River as it flows south toward the Danube, and extended eastward to the Bohemian forest. The boundaries of the Palatinate varied with the political and dynastic fortunes of the counts palatine. Source: https://www.britannica.com/place/Palatinate
