Louis V (c. 966 or 967 – 22 May 987), also known as Louis the Do-Nothing (French: Louis le Fainéant), was a king of West Francia from 979 (co-reigning first with his father Lothair until 986) to his early death in 987. During his reign, the nobility essentially ruled the country. Dying childless, Louis V was the last Carolingian monarch in West Francia.
