Carloman II ( 866 – 6 December 884) was the King of West Francia (future France) from 879 until his death. A member of the Carolingians, he and his elder brother Louis III, divided the kingdom between themselves and ruled jointly until the latter's death in 882. Thereafter Carloman ruled alone until his own death. He was the second son of King Louis the Stammerer and Queen Ansgarde.
Early life

Carloman II was born around 866 as the second son of King Louis II the Stammerer and Ansgarde of Burgundy. His grandfather was Charles the Bald, himself a grandson of Charlemagne, placing him firmly within the prestigious Carolingian dynasty. Carloman and his older brother Louis were born while their father was still King of Aquitaine, before Louis the Stammerer ascended to the throne of West Francia.

Upon Louis the Stammerer's death, some Frankish nobles advocated electing Louis III as the sole king, but eventually both brothers were elected kings. They were both crowned in September 879. Some doubts were cast upon the legitimacy of their birth, but these disappeared after their victory over the Vikings on November of that year.
After taking Kortrijk in November 880, the Vikings raided Arras and Cambrai in December, and later in 881, they sacked Amiens and Corbie. On August 3, 881, Carloman and his brother Louis III achieved a significant victory against the Vikings at the Battle of Saucourt-en-Vimeu.
Sole Rule
When Louis III died unexpectedly in August 882 at the young age of 19, Carloman became the sole ruler of West Francia.
The kingdom Carloman inherited was in a deplorable condition, partly due to repeated incursions from Viking raiders. His power was significantly limited by rebellious nobles, especially in Burgundy. Despite these challenges, Carloman continued to defend his territories and maintain the governance structures established by his Carolingian predecessors.
Death
Carloman II died near Les Andelys while hunting on December 884. He was accidentally stabbed in the leg by his servant Bertoldus while they were attacked by a wild boar. Carloman survived but died seven days later, He was only about 18 years old.
