This name derives from the Old High German name “Chlothar / Chlodochar”, composed of two elements: “*hlūdaz” (to hear, loud, sound, noise / famous) and “*harjaz” (army, army leader, commander, warrior). In turn, the name means “famous warrior, army (kingdom of Lothar)”. Lothar I was the Emperor of the Romans (817–855), co-ruling with his father until 840, and the King of Bavaria (815–817), Italy (818–855) and Middle France (840–855). The territory of Lorraine (German: Lothringen) is named after him. Lorraine is the French form of the Latin place name "Lotharingia", the territory of the people of Lothar.
