Upon the death of Prince Elector Ludwig IV., Friedrich I., prince elector from the House of Wittelsbach (*1425, +1476), called "the Victorious", assumed guardianship of Ludwig's 13-month-old son, the future Prince Elector Philipp of the Pfalz.
At the same time, he was officially appointed regent and, with the approval of the other six prince electors, was named "Imperial Steward and Prince Elector of the Holy Roman Empire" for life.
Friedrich's natural son, Ludwig, was elevated to the status of an imperial count on 27 February 1494. After his father's death, he inherited the county of Löwenstein in Württemberg. He was known as Ludwig of Bavaria and died in 1524.
