Charles III, known as the Simple or the Straightforward, was a Carolingian monarch who reigned as the King of West Francia from 898 to 922. Posthumously born in 879 to Louis the Stammerer and Adelaide of Paris, his life was defined by the struggle to consolidate royal authority against assertive Frankish nobility and persistent Viking incursions.
Ascension to the Throne
Following the death of his half-brother Carloman II in 884, the young Charles was bypassed by the nobility in favor of the Emperor Charles the Fat and later the Robertian king Odo. Protected by Ranulf II of Aquitaine during his youth, Charles finally secured his position in 893 when a supportive faction crowned him at Reims Cathedral. He officially assumed the kingship of West Francia in 898 following the death of Odo.

In 911, Viking forces led by Rollo besieged Paris and Chartres. After a notable victory near Chartres, Charles initiated negotiations that culminated in the Treaty of Saint-Clair-sur-Epte. This agreement established the Duchy of Normandy, granting the Vikings territory between the river Epte and the sea in exchange for their loyalty. As part of the settlement, Rollo underwent baptism and married Charles's daughter, Gisela.
Ambitions in Lotharingia
Following the death of Louis the Child in 911, the nobility of Lotharingia declared Charles their king, seeking an alternative to the non-Carolingian Conrad I of East Francia. Charles moved to solidify this alliance, having previously married the Lotharingian noblewoman Frederuna in 907. Despite defending the region against incursions from Conrad I, his hold on Lotharingia faltered as local leaders eventually shifted their loyalties toward East Francia.
Revolt and Imprisonment
Charles faced mounting aristocratic opposition due to his overt favoritism toward the nobleman Hagano, whom he endowed with church lands at the expense of established barons. In 922, Robert of Neustria led a revolt that resulted in his own election as king. Charles was subsequently captured in 923 following his defeat at the Battle of Soissons and imprisoned in a castle at Péronne under the guard of Herbert II of Vermandois. He remained in captivity until his death in 929.
