Input: Context: Louis III ( 863/65 -- 5 August 882 ) was the king of West Francia ( France ) from 879 until his death . The eldest son of Louis the Stammerer and his first wife , Ansgarde , he succeeded his father and ruled jointly with his younger brother , Carloman II , who became sole ruler on Louis 's death . Louis 's short reign was marked by military success . Louis was born while his father was still just King of Aquitaine and his grandfather , Charles the Bald , was ruling West Francia . Some doubts were raised as to their legitimacy , since their parents had married secretly and Ansgarde was later repudiated at Charles ' insistence . When Charles ( 877 ) and then the elder Louis died within two years , some nobles advocated electing the younger Louis as sole king , but another party favoured each brother ruling a separate sphere of the country . In September 879 Louis was crowned at Ferrières . In March 880 at Amiens the brothers divided their father 's kingdom , Louis receiving the northern part , called Neustria or sometimes simply Francia . One of Charles the Bald 's most trusted lieutenants , Duke Boso had renounced his allegiance to both brothers and had been elected King of Provence . In the summer of 880 Carloman and Louis marched against him and captured Mâcon and the northern part of Boso 's realm . They united their forces with those of their cousin Charles the Fat , then ruling Germany and Italy , and unsuccessfully besieged Vienne from August to November . In 881 Louis achieved a momentous victory against Viking pirates , whose harassments had been ongoing since his grandfather 's reign , at the Battle of Saucourt - en - Vimeu . Within a year of the battle an anonymous poet had celebrated it and the king , for both his prowess and piety , in the Old High German short poem Ludwigslied . Louis died on 5 August 882 at Saint - Denis in the centre of his realm , having fallen from his horse whilst chasing a girl with amorous intent . He hit the lintel of a door with his head while mounting his horse and fractured his cranium on impact , which led to his death . Since he had no children , his brother Carloman became the sole king and the victor of Saucourt was buried in the royal mausoleum of the Basilica of St Denis ., Carloman I, also "Karlmann" (28 June 751  4 December 771) was king of the Franks from 768 until his death in 771. He was the second surviving son of Pepin the Short and Bertrada of Laon and was a younger brother of Charlemagne. Little is known of him, except such as touches upon his more famous father and brother. Carloman is mainly regarded by historians as Charlemagne's first steps towards acquiring the Holy Roman Empire, as his death allowed Charlemagne to take all of Francia and begin his expansion into other kingdoms., Carloman II (c. 866 - 12 December 884), King of West Francia, was the youngest son of King Louis the Stammerer and Ansgarde of Burgundy, and became king jointly with his brother Louis III of France on his father's death in 879. Initially some Frankish nobles advocated electing Louis III as the sole king, but eventually both brothers were elected kings. Although some doubts were cast upon the legitimacy of their birth, the brothers obtained recognition and in March 880 divided their father's realm at Amiens, Carloman receiving southern Kingdom of Burgundy and Kingdom of Aquitaine., Ermentrude of Orléans (27 September 823  6 October 869) was Queen of the Franks by her marriage to Charles the Bald, Holy Roman Emperor and King of West Francia. She was the daughter of Odo, Count of Orléans and his wife Engeltrude., Ansgarde of Burgundy (d. 880/882) was a French queen of Aquitaine, but never of West Francia, the daughter of Hardouin of Burgundy. She secretly married Louis II of France before he was king; her sons became Louis III and Carloman II of France., Louis the Stammerer (1 November 846  10 April 879) was the King of Aquitaine and later the King of West Francia. He was the eldest son of emperor Charles the Bald and Ermentrude of Orléans. Louis the Stammerer was physically weak and outlived his father by only two years., Subject: louis iii of france, Relation: mother, Options: (A) ansgarde of burgundy (B) bertrada of laon (C) ermentrude of orléans
