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.
