Henry II, Count of Vianden

Henry II of Vianden (died 1337) was the last male of his house. Son of Count Philip II, he held the county from 1315 or 1316 jointly with his sister Adelaide, and in 1335 or 1336 he married Marie of Namur.

In 1337 he set out for the Holy Land by way of Cyprus with his brother-in-law Philip III of Namur, but at Famagusta their conduct was so dissolute that the townspeople killed them and their companions. Both were buried in the town's Franciscan church.

Henry's infant daughter Marie inherited Vianden; in 1417 her daughter Elisabeth gave up her rights to Engelbert I of Nassau-Dillenburg, a grandson of Adelaide, who became Count of Vianden.
