Louis the Blind (c. 880 – 5 June 928) was king in Provence and Lower Burgundy from 890 to 928, and also king of Italy from 900 to 905, and also the emperor between 901 and 905, styled as Louis III since his grandfather was styled as Louis II from 844–875. His father was king Boso, from the Bosonid family, and his mother was Ermengard, a Carolingian princess & only child of Emperor Louis II. In 905, he was blinded and lost Italy, retreating to his remaining domains in Provence and Lower Burgundy. In historiography, he is styled as King of Provence, or King of Burgundy.
