Luitpold, Prince Regent of Bavaria (12 March 1821 – 12 December 1912), was the de facto ruler of Bavaria from 1886 to 1912, due to the incapacity of his nephews, King Ludwig II for three days and King Otto for 26 years. At the age of fourteen Luitpold joined the Bavarian Army and was promoted Captain of the Artillery in 1835. During the revolutions of 1848 Prince Luitpold mediated and facilitated an audience of discontented citizens with his father. During the rule of his brother Maximilian II (1848–64), Luitpold did not play a significant political role.
