About Baldwin I "Iron-Arm", count of Flanders

Baldwin I, byname Baldwin Iron-arm, French Baudouin Bras-de-fer, Flemish Boudewijn De Ijzere Arm (died 879), the first ruler of Flanders. A daring warrior under Charles II the Bald of France, he fell in love with the king’s daughter Judith, the youthful widow of two English kings, married her (862), and fled with his bride to Lorraine. Charles, though at first angry, was at last conciliated, and made his son-in-law margrave (Marchio Flandriae) of Flanders (864), which he held as a hereditary fief. The Norsemen were at this time continually devastating the coastlands, and Baldwin was entrusted with this outlying borderland in order to defend it. He was the first of a line of strong rulers of Flanders, who early in the 10th century exchanged the title of margrave for that of count.


Institution of Baldwin I 'Bras de Fer', the first count of Flanders by Charles the Bald, the Frankish king. Baldwin I (probably 830s – 879), also known as Baldwin Iron Arm (the epithet is first recorded in the 12th century), was the first count of Flanders.

At the time Baldwin first appears in the records he was already a count, presumably in the area of Flanders, but this is not known. Count Baldwin rose to prominence when he eloped with princess Judith, daughter of Charles the Bald, king of West Francia. Judith had previously been married to Æthelwulf and his son (from an earlier marriage) Æthelbald, kings of Wessex, but after the latter's death in 860 she had returned to France.

Around Christmas 861, at the instigation of Baldwin and with her brother Louis' consent Judith escaped the custody she had been put under in the city of Senlis, Oise after her return from England. She fled north with Count Baldwin. Charles had given no permission for a marriage and tried to capture Baldwin, sending letters to Rorik of Dorestad and Bishop Hungar, forbidding them to shelter the fugitive. After Baldwin and Judith had evaded his attempts to capture them, Charles had his bishops excommunicate the couple. Judith and Baldwin responded by traveling to Rome to plead their case with Pope Nicholas I. Their plea was successful and Charles was forced to accept. The marriage took place on 13 December 862 in Auxerre. By 870 Baldwin had acquired the lay-abbacy of St. Pieter in Ghent and is assumed to have also acquired the counties of Flanders and Waasland, or parts thereof by this time. Baldwin developed himself as a very faithful and stout supporter of Charles and played an important role in the continuing wars against the Vikings. He is named in 877 as one of those willing to support the emperor's son, Louis the Stammerer. During his life Baldwin expanded his territory into one of the major principalities of Western Francia, he died in 879 and was buried in the Abbey of St-Bertin, near Saint-Omer.

Family[edit source | editbeta]

Baldwin was succeeded by his and Judith's son, Baldwin II (c. 866 – 918). The couple's first son, Charles, named after his maternal grandfather, died at a young age. His third son Raoul (Rodulf) (c. 869 – murdered 896) became Count of Cambrai around 888, but he and his brother joined king Zwentibold of Lotharingia in 895. In 896 they attacked Vermandois and captured Arras, Saint-Quentin and Peronne, but later that year Raoul was captured by count Heribert and killed.

Legendary origins[edit source | editbeta]

Medieval stories held that Baldwin was a scion of the Great Forestiers of Flanders a direct descendent of Lydéric who received his fiefdoms directly from Dagobert I -Merovingian King of the Franks- in 621 AD.. References[edit source | editbeta]
