Henry II (1206–1229) was the margrave of Namur from 1226 until his death.
He was the third son of the Peter II of Courtenay, Latin Emperor, and Yolanda, countess of Namur.
[1] When his eldest brother, Philip II, Marquis of Namur died in 1226 without an heir, his second brother Robert was already Latin Emperor in Constantinople, so Henry became the new Margrave of Namur.
[citation needed] At the time of his succession he was in France, under the guardianship of Enguerrand III, Lord of Coucy.
[citation needed] Henry died himself one year later without children, and he was succeeded by his sister Margaret, who was married to Henry, count of Vianden.
