Louis I

Louis I may refer to:

Louis I of Hungary

Louis I, also Louis the Great (Hungarian: Nagy Lajos; Croatian: Ludovik Veliki; Slovak: Ľudovít Veľký) or Louis the Hungarian (Polish: Ludwik Węgierski; 5 March 1326 – 10 September 1382), was King of Hungary and Croatia from 1342 and King of Poland from 1370. He was the first child of Charles I of Hungary and his wife, Elizabeth of Poland, to survive infancy. A 1338 treaty between his father and Casimir III of Poland, Louis's maternal uncle, confirmed Louis's right to inherit the Kingdom of Poland if his uncle died without a son. In exchange, Louis was obliged to assist his uncle to reoccupy the lands that Poland had lost in previous decades. He bore the title of Duke of Transylvania between 1339 and 1342 but did not administer the province.

Louis was of age when succeeded his father in 1342, but his deeply religious mother exerted a powerful influence on him. He inherited a centralized kingdom and a rich treasury from his father. During the first years of his reign, Louis launched a crusade against the Lithuanians and restored royal power in Croatia; his troops defeated a Tatar army, expanding his authority towards the Black Sea. When his brother, Andrew, Duke of Calabria, husband of Queen Joanna I of Naples, was assassinated in 1345, Louis accused the queen of his murder and punishing her became the principal goal of his foreign policy. He launched two campaigns to the Kingdom of Naples between 1347 and 1350. His troops occupied large territories on both occasions, and Louis adopted the styles of Neapolitan sovereigns (including the title of King of Sicily and Jerusalem), but the Holy See never recognized his claim. Louis's arbitrary acts and atrocities committed by his mercenaries made his rule unpopular in Southern Italy. He withdrew all his troops from the Kingdom of Naples in 1351.

Ludwig I of Bavaria

Ludwig I (also rendered in English as Louis I; 25 August 1786 – 29 February 1868) was king of Bavaria from 1825 until the 1848 revolutions in the German states.

Crown prince

Born in Hôtel des Deux-Ponts in Strasbourg, he was the son of Count Palatine Maximilian Joseph of Zweibrücken (later Maximilian I Joseph of Bavaria) by his first wife Augusta Wilhelmine of Hesse-Darmstadt. At the time of his birth, his father was an officer in the French army stationed at Strasbourg. He was the godson and namesake of Louis XVI of France.

On 1 April 1795 his father succeeded Ludwig's uncle, Charles II, as duke of Zweibrücken, and on 16 February 1799 became Elector of Bavaria and Count Palatine of the Rhine, the Arch-Steward of the Empire, and Duke of Berg on the extinction of the Sulzbach line with the death of the elector Charles Theodore. His father assumed the title of King of Bavaria on 1 January 1806.

Starting in 1803 Ludwig studied in Landshut where he was taught by Johann Michael Sailer and in Göttingen. In October 1810, he married Therese of Saxe-Hildburghausen (1792–1854), the daughter of Frederick, Duke of Saxe-Hildburghausen. The wedding was the occasion of the first ever Oktoberfest.
