Life [
edit]
His introduction to military life came as he was made a knight in a conflict between his father and the 
Bishop of Metz. He then served 
Frederick III, Duke of Lorraine. He was preparing to go on crusade when his father died.
In 1284 
Joan I of Navarre, countess of Champagne, had married the future 
Philip IV of France, making the county of Bar adjacent to the 
French royal domain. Henry's reaction was a marriage to 
Eleanor, daughter of 
Edward I of England. When war broke out in short order between France and England, Henry was drawn in. The fighting ceased after the 1301 
Treaty of Bruges. Under its terms, Henry gave up some fortresses and paid homage to 
Philip for part of his lands, then called the 
Barrois mouvant. He also undertook to fight in 
Cyprus against the Muslim forces.
Henry therefore made his way to the 
Kingdom of Naples. In assisting 
Charles II of Naples against the invading forces of 
Frederick I of Sicily, he was wounded in fighting, and died soon afterwards.
