The House of Arenberg is an aristocratic lineage that is constituted by three successive families who took their name from Arenberg, a small territory of the Holy Roman Empire in the Eifel region. The inheritance of the House of Croÿ-Aarschot made the Arenbergs the wealthiest and most influential noble family of the Habsburg Netherlands. The Arenbergs were mediatized in 1811.
The current head of the house bears the title of Duke of Arenberg, while all other members are princes or princesses. They all enjoy the style of Serene Highness.
The marriage contract in 1547 between Margaret de la Marck, Countess of Arenberg, and Jean de Ligne-Barbançon stipulated that their offspring would abandon the name of Ligne and adopt the name and arms of Arenberg. On 5 March 1576, Emperor Maximilian II raised Margaret and her son Charles to the rank of Princely Counts (in German: Gefürstete Graf). As such, the Arenbergs sat and voted on the bench of secular princes in the Imperial Diet. On 9 June 1644, Emperor Ferdinand III bestowed the title of Duke of Arenberg on Charles' grandsons, Philip-Francis and Charles-Eugene, as well as to all legitimate descendants of Charles and his brother Robert of Arenberg, prince of Barbançon.
Meanwhile, the marriage of Princely Count Charles to Anne de Croÿ, the sister and heiress of the last Croÿ Duke of Aarschot, had brought the Arenbergs a series of titles, as well as vast estates in the Habsburg Netherlands in 1612. The senior title was that of Duke of Aarschot. It had been created in 1534, it was the first (and until 1627 the only) ducal title in the Netherlands, and it carried the dignity of a Spanish Grandee. The lands of the Arenbergs gave them a seat in the second estate of the Provincial States of Brabant and of Hainaut.
