Ottheinrich initially ruled from Pfalz-Neuburg.
Ottheinrich von Bayern was the son of Ruprecht der Tugendhafte (Rupert the Good) and Elisabeth von Bayern-Landshut, a grandson of Prince-Elector Philipp von der Pfalz. In 1522, together with his brother, he assumed rule of the newly founded principality of Pfalz-Neuburg, which he later ruled alone. Not until 1556, after the death of his uncle and previous guardian, Friedrich II von der Pfalz, did Ottheinrich finally assume rule as Prince-Elector Palatine, a seat he then held until his death in 1559.
Building was a passion.
Already in the early years of his rule in Neuenburg, Ottheinrich began expanding his castle into a Renaissance castle, thereby acquiring great debt. His creation, the Ottheinrich’s Wing, which also bears his name, can still be admired in Heidelberg today. Ottheinrich was also a great patron and lover of the arts: He commissioned or purchased prominent works of fine art, painting, music and book art. His library, the Bibliotheca Palatina, is still considered one of the most important libraries of its time.
In the early years, Ottheinrich concentrated primarily on his structures and their decor, such as the Neuburg Palace, which also boasted a pleasure garden and a menagerie with exotic animals. In 1546, when he was forced into exile and fled to Heidelberg, he began collecting books and sheet music, coins and medals. He was interested in "antiquarian" books and was able to bring manuscripts from various monasteries, such as Lorsch Monastery, to Heidelberg. He had his books re-bound according to his own ideas.
Andreas Osiander introduced the prince-elector to the Protestant faith.
In 1542, Ottheinrich, influenced by theologian Andreas Osiander, converted to evangelical faith. Via a decree, he implemented the Protestant faith into his principality, Pfalz-Neuburg. This was part of the reason why his principality was temporarily occupied by imperial troops during the Schmalkaldic War and why Ottheinrich had to flee in exile to Heidelberg. After coming into power in Heidelberg in 1556, he also implemented the Lutheran faith in the Electoral Palatinate. However, he was unable to complete his reform, due to his early death.
Ottheinrich first introduced Johannes Brenz's Württemberg Church Order to the Electoral Palatinate. As suitable workforces for the reorientation of the church and university were lacking in his own state, experts were brought in from outside. This formed the basis for the various doctrines of German Protestantism in the Electoral Palatinate, which became noticeable after Ottheinrich's death in the form of conflict. His successor, Friedrich III, gave growing support to the reformed faith. He implemented the "Heidelberg Catechism," which the Palatinate followed, but which prompted the Lutherans to leave the state.
Prince-Electors Ottheinrich and Friedrich III were extremely important figures for the religious affiliations of the Electoral Palatinate.
