Luitpold was born in Würzburg, the third son of King Ludwig I of Bavaria and his wife, Therese of Saxe-Hildburghausen. He was the younger brother of King Maximilian II of Bavaria and of King Otto of Greece. Luitpold was in line to succeed to the throne of the Kingdom of Bavaria, and was also heir presumptive to the throne of Greece, since his brother Otto had no children. However, the Greek constitution required that Otto's heir should belong to the Greek Orthodox Church. Otto was deposed in 1862 and replaced by Prince William of Denmark, who became George I, King of the Hellenes. Otto died in 1867, leaving Luitpold and his descendants as representatives of Otto's claim. However, Luitpold never pursued that claim.
