Thegan's Vita Hludowici Imperatoris names (in order) "Hlutharius, Pippinus, Hludowicus" as sons of Emperor Louis and his wife Ermengard. Under the Ordinatio Imperii promulgated by Emperor Louis in 817, Louis received "Baioariam et Carentanos, et Beheimos et Avaros, atque Sclavos qui ab orientali parte Baioariæ sunt…et duas villas…in pago Nortgaoe Luttraof et Ingoldesstat", specifying that he was to be named king. He fought with his father and his brothers, joining the rebellions in 831 and 833. In the settlement of 833, he received Alemannia, Alsace and Rhetia (taken from his half-brother Charles II "le Chauve", as well as Thuringia and Saxony. His father obliged him to leave these additional territories in 839, confining his rule once more to Bavaria. Following the accession of his brother Lothaire as sole emperor after their father's death in 840, Ludwig allied himself with his half-brother Charles II "le Chauve". Together they defeated Emperor Lothaire at Fontenoy-en-Puisaye, near Auxerre 25 Jun 841.

Under the partition of territories agreed under the Treaty of Verdun 11 Aug 843, Louis was installed as LUDWIG II "der Deutsche" King of the East Franks. When Charles II "le Chauve" King of the West Franks was faced with widespread rebellion, King Ludwig II invaded his kingdom in Aug 858 but was defeated 15 Jan 859 in the Laonnais and forced to withdraw. In 865, King Ludwig agreed with King Charles "le Chauve" the future division of the territories of Lothaire II King of Lotharingia, but on the latter's death in 869 King Charles invaded Lotharingia before Ludwig could assert his rights. A settlement was reached at Meerssen in Aug 870 under which Ludwig received Alsace and other territory along the Rhine, in effect succeeding as LUDWIG I King of Lotharingia [part].

The necrology of Prüm records the death "876 5 Kal Sep" of "Ludvicus imperator frater Ludvici imperatoris". ¹
