Louis II (French: Louis le Begue; Louis II, November 1, 846 -- April 10, 879) was the eldest son of Charles II (Charles the Bald), emperor of the Franks and king of the West Franks, and his wife, Eumentrude of Orleans. King of the Carolingian dynasty of Aquitaine Louis III, reigned 866 -- 879) and Carolingian king of West France (reigned 877 -- 879), but he did not succeed his father and was crowned emperor, leaving the so-called "Emperor of the Romans" vacant for the first time since Charlemagne, when the Carolingian monarchs monopolized the throne.

His eldest brother, Charlie, was deeply loved by his father and was crowned king of Aquitaine in October 855 at the age of 6. Louis, who was 3 years older, did not receive any crown. The title 'King of Aquitaine' was a title that Bald Charles had intended to acquire but did not acquire since the death of his uncle Pippin I of Aquitaine in 838, and his ancestor Charles the Great also gave this title to his successor, the devout Louis. Bald Charlie gave this title to the child Charlie, indicating that he preferred the second son over the eldest son, and even intended to establish the second son as the heir.
However, Louis was relatively fortunate. While his father was still alive, his younger brother and child Charlie passed away on September 29, 866, leaving no heir. Louis succeeded his younger brother to the throne and became King Louis III of Aquitaine.

After the death of Bald Charles on October 5 or October 6, 877, Louis inherited the throne of the West Franks and was officially named "King of the Franks [3] Louis II", nominally inheriting all of the territory of the West Franks except for Provence, which was gifted to Poisson of Provence by his father during his lifetime. On December 8th of the same year, he was crowned by Archbishop Inkmar of Gombigne and officially ascended to the throne.
Louis II had little ambition for the title of emperor of the already divided Frankish Empire. On September 7, 878, when Pope John VIII was attending a conference in Truva, he crowned Louis II for the second time. The Pope even wanted to crown him as the Frankish Emperor (often equivalent to the Holy Roman emperor) to inherit his father's bald Charles, but Louis II refused.

Louis II was a mediocre monarch with a weak constitution, and he also died two years after his father, bald Charlie, so he made little political achievements. He is portrayed as "a simple and kind person, a lover of peace, justice, and faith", who has been subject to the aristocracy throughout his reign. In 878, he gifted the hairy Wilfred with the three principalities of Barcelona, Jerona, and Besaru in the Spanish border region. His last major action was to fight against the Vikings (i.e. Vikings) who ravaged Europe. But shortly after the expedition began, he fell ill and passed away on April 9 or April 10, 879, at the age of 33, in Gongbine.

After the death of Louis II, according to Frankish tradition, the territory of the Kingdom of West Franck (later France) was divided between him and his two sons, Louis III and Caroline II, who were born to his first wife. The two brothers ruled together. The land of Lorraine was acquired by his cousin, King Louis II of Saxony, and became the Kingdom of Lorraine (also known as Lorraine). Louis II of Saxony belonged to the East Frankish (later German) branch of the Carolingian dynasty, and from then on, Germany and France engaged in a long-term struggle for Lorraine. Lorraine also became the main battlefield for the two countries to compete for European hegemony.
