Louis IV of France

Louis IV (920/921 – 10 September 954), called d'Outremer or Transmarinus ("From overseas"), reigned as King of West Francia from 936 to 954. A member of the Carolingian dynasty, he was the only son of king Charles the Simple and his second wife Eadgifu of Wessex, daughter of King Edward the Elder of Wessex. His reign is mostly known thanks to the Annals of Flodoard and the later Historiae of Richerus.

Louis was born to King Charles III and his second wife Eadgifu, in the heartlands of West Francia's Carolingian lands between Laon and Reims in 920 or 921. He was descended both from Charlemagne and King Alfred the Great. From his father's first marriage with Frederuna (d. 917) he had six older half-sisters.

After the dethronement and capture of Charles the Simple in 923, following his defeat at the Battle of Soissons, queen Eadgifu and her infant son took refuge in Wessex (for this he received the nickname of d'Outremer) at the court of her father King Edward, and after Edward's death, of her brother King Æthelstan. Young Louis was raised in the Anglo-Saxon court until his teens. During this time he enjoyed legendary stories about Edmund the Martyr (king of East Anglia), an ancestor of his maternal family who had heroically fought against the Vikings.

Louis became the heir to the western branch of the Carolingian dynasty after the death of his captive father in 929, and in 936, at the age of 15, was recalled from Wessex by the powerful Hugh the Great, margrave of Neustria, to succeed the Robertian King Rudolph who had died.

Once he took the throne, Louis wanted to free himself from the tutelage of Hugh the Great, who, with his title of duke of the Franks was the second most powerful man after the King. In 939, the young monarch attempted to conquer Lotharingia; however, the expedition was a failure and his brother-in-law, King Otto I of East Francia counterattacked and besieged the city of Reims in 940. In 945, following the death of William I Longsword, duke of Normandy, Louis tried to conquer his lands, but was captured by the Normans and handed over to Hugh the Great.

The Synod of Ingelheim in 948 allowed the excommunication of Hugh the Great and released Louis from his long tutelage. From 950 Louis gradually imposed his rule in the northeast of the kingdom, building many alliances (especially with the counts of Vermandois) and under the protection of the Ottonian kingdom of East Francia.

In spring of 936 Hugh the Great sent an embassy to Wessex inviting Louis to "come and take the head of the kingdom" (Flodoard). King Æthelstan, his uncle, after forcing the embassy to swear that the future king will have the homage of all his vassals, permitted him the return home with his mother Eadgifu, some bishops and faithful servants. After a few hours of sea journey, Louis received the homage of Hugh and some Frankish nobles on the beach of Boulogne, who kissed his hands. Chronicler Richerus gives us an anecdote about this first encounter:

Louis and his court then began the trip to Laon where the coronation ceremony was to take place. Louis IV was crowned king by Archbishop Artald of Reims on Sunday, 19 June 936, probably at the Abbey of Notre-Dame and Saint-Jean in Laon, perhaps at the request of the King since it was a symbolic Carolingian town and he was probably born there.
