Overview
Charles III (17 September 879 – 7 October 929), called the Simple or the Straightforward (from the Latin Carolus Simplex), was the king of West Francia from 898 until 922 and the king of Lotharingia from 911 until 919–923. He was a member of the Carolingian dynasty.
Early life
Charles was the third and posthumous son of King Louis the Stammerer by his second wife Adelaide of Paris. As a child, Charles was prevented from succeeding to the throne at the time of the death in 884 of his half-brother, king Carloman II. Instead, Frankish nobles of the realm asked his cousin, Emperor Charles the Fat, to assume the crown. He was also prevented from succeeding the unpopular Charles the Fat, who was deposed in November 887 and died in January 888, although it is unknown if his overthrow was accepted or even made known in West Francia before his death. The nobility then elected Odo, the hero of the Siege of Paris (885–886) as the new king, although there was a faction that supported claims of Guy III of Spoleto. The young Charles was put under the protection of Ranulf II, the Duke of Aquitaine, who may have tried to claim the throne for him and in the end used the royal title himself until making peace with Odo.
King of West Francia
In 893, at the age of 14, Charles was crowned by a faction opposed to the rule of Odo at the Reims Cathedral, becoming monarch of West Francia only after the death of Odo in 898.
In 911, a group of Vikings led by Rollo besieged Paris and Chartres. After a victory near Chartres on 26 August, Charles decided to negotiate with Rollo, resulting in the Treaty of Saint-Clair-sur-Epte which created the Duchy of Normandy. In return for the Vikings' loyalty, they were granted all the land between the river Epte and the sea, as well as Duchy of Brittany, which at the time was an independent country which West Francia had unsuccessfully tried to conquer. Rollo also agreed to be baptised and to marry Charles's daughter Gisela.
