Godefroi, Duc de Basse-Lorraine

Godfrey I, called "the Bearded", "the Courageous" or "the Great" was the landgrave of Brabant, Count of Brussels and Leuven (Louvain), Duke of Lower Lorraine, and margrave of Antwerp.

Godfrey first came into conflict with Otbert, Bishop of Li�ge, over the county of Brunengeruz that both claimed. In 1099, Emperor Henry IV allotted the county to the bishop, who entrusted it to Albert III, Count of Namur. Godfrey arbitrated a dispute between Henry III of Luxembourg and Arnold I, Count of Loon, over the appointment of the abbot of Sint-Truiden.

Godfrey was in favour with the emperor and defended his interests in Lorraine. In 1102, he stopped Robert II of Flanders, who was invading the Cambraisis. After the death of the emperor in 1106, his son and successor, Henry V, who had been in rebellion, decided to avenge himself on his father's partisans. Duke Henry of Lower Lorraine was imprisoned and his duchy confiscated and given to Godfrey. After Henry escaped from prison, he tried to retake his duchy and captured Aachen, but ultimately failed.

In 1114, during a rift between the emperor and Pope Paschal II, Godfrey led a revolt in Germany. In 1118, the emperor and the duke were reconciled. In 1119, Baldwin VII of Flanders died heirless and Flanders was contested between several claimants, one of whom, William of Ypres, had married a niece of Godfrey's second wife. Godfrey supported William, but could not enforce his claim against that of Charles the Good. Also dead in that year was Otbert. Two separate men were elected to replace him and Godfrey again sided with the loser.

By marrying his daughter Adeliza to Henry I of England, who was also the father-in-law of the emperor, he greatly increased his prestige. However, Henry V died in 1125 and Godfrey supported Conrad of Hohenstaufen, the duke of Franconia, against Lothair of Supplinburg. Lothair was elected. Lothair withdrew the duchy of Lower Lorraine and granted it to Waleran, the son of Henry, whom Henry V had deprived in 1106. Nonetheless, Godfrey maintained the margraviate of Antwerp and retained the ducal title (which would in 1183 become Duke of Brabant).

After the assassination of Charles the Good in 1127, the Flemish succession was again in dispute. William Clito prevailed, but was soon fraught with revolts. Godfrey intervened on behalf of Thierry of Alsace, who prevailed against Clito. Godfrey continued to war against Li�ge and Namur.
