Bavaria-Ingolstadt (or German: Oberbayern-Ingolstadt) was a duchy which was part of the Holy Roman Empire from 1392 to 1447.[1]
After the death of Stephen II in 1375, his sons Stephen III, Frederick, and John II jointly ruled Bavaria-Landshut. After seventeen years, the brothers decided to formally divide their inheritance. John received Bavaria-Munich, Stephen received Bavaria-Ingolstadt, while Frederick kept what remained of Bavaria-Landshut.
After Stephen's death in 1413, Louis VII assumed his father's throne. In 1429 parts of Bavaria-Straubing were united with Bavaria-Ingolstadt. Louis reigned until his own son, Louis VIII, usurped his throne in 1443 and delivered him to their enemy, Henry XVI, duke of Bavaria-Landshut. Louis VIII died two years later. Louis VII died in captivity. With no heir, Bavaria-Ingolstadt was returned to Bavaria-Landshut.[2]
Bavaria-Ingolstadt was cobbled together from diverse, non-contiguous territories in Bavaria. The capital was Ingolstadt and included the territories around it: Schrobenhausen, Aichach, Friedberg, Rain am Lech and Höchstädt an der Donau. In addition, Bavaria Ingolstadt incorporated the following towns:
