In 1183, Henry took the title of duke of Brabant. Upon the death of his father in 1190, King
Henry VI confirmed the elevation of Brabant, while he
de facto abolished the Duchy of
Lower Lorraine by creating the empty title of a
duke of Lothier. Duke Henry sought to expand his power and soon picked several quarrels with the Count
Baldwin V of Hainaut. He also was in opposition to the German king (emperor from 1191) when his brother
Albert of Louvain was elected
bishop of Liège and murdered shortly afterwards. Further conflicts with Duke
Henry III of Limburg and Count
Otto I of Guelders followed, before in mid-1197 Henry of Brabant joined the
Crusade of Henry VI as one of the leaders. In October of the same year he took part in the recapture of
Beirut and, then moved to
Jaffa with the crusaders: however, before reaching the city he got news of the death of the ruler of the Kingdom of Jerusalem, Count
Henry II of Champagne, and he returned to
Acre. Here he acted as regent until the arrival of the new king,
Aimery of Cyprus. Back in Germany after the emperor's death in September 1197, Duke Henry supported the
election of the
Welf candidate
Otto IV, the fiancé of his daughter
Maria, who rivalled with the
Hohenstaufen scion
Philip of Swabia. He fought against Philip's seconders Count
Dirk VII of Holland and Count Otto of Guelders, however, he switched sides in 1204, when he and King
Philip II of France backed Philip against Otto. In 1208, after the assassination of Philip, Henry was proposed as successor by King Philip II. In the war which followed, he finally reached a reconciliation with Emperor Otto IV. Together they fought against King Philip in the 1214
Battle of Bouvines, but the two were defeated. In 1213, Duke Henry also suffered a heavy defeat against the
Bishopric of Liège in the
Battle of Steppes. From 1217 to 1218 he joined the
Fifth Crusade to
Egypt. Under Henry I, there was town policy and town planning. His attention went out to those regions that lent themselves to the extension of his sovereignty and in some locations he used the creation of a new town as an instrument in the political organisation of the area. Among the towns to which the duke gave city rights and trade privileges were
's-Hertogenbosch and
Eindhoven. In 1234, he participated in the
Stedinger Crusade. In 1235,
Emperor Frederick II appointed Henry to travel to
England to bring him his fiancée
Isabella, daughter of
King John of England. Henry fell ill on his way back and died at
Cologne. He was buried in
Saint Peter's Church at Leuven where his Late Romanesque effigy can still be seen. ==Marriages==
