The House of Arenberg is an aristocratic lineage that is constituted by three successive families that took their name from Arenberg, a small territory of the Holy Roman Empire in the Eifel region.[a] The inheritance of the House of Croÿ-Aarschot made the Arenbergs the wealthiest and most influential noble family of the Habsburg Netherlands. The family's Duchy of Arenberg was a Sovereign State until it was mediatized in 1810. As such, the Arenbergs belong to the small group of families that constitute the Hochadel (German for 'high nobility').
The current head of the house bears the title of Duke of Arenberg, while all other members are princes or princesses.[1] They all enjoy the style of Serene Highness.
In 1827, Prince Pierre d'Arenberg, third son of the 6th Duke of Arenberg, was granted the French noble title of duke by King Charles X and was made a hereditary peer of France. His descendants form a French cadet branch of the family, the head of which holds the French ducal title (duc d'Arenberg).
