Charles de Ligne, 2nd Prince of Arenberg

Charles of Arenberg was the eldest son of Jean de Ligne and Margaretha von der Mark, countess of Arenberg. As his mother was the sister and sole heiress of Robert III von der Marck-Arenberg, the marriage contract of his parents stipulated that he would bear the title, name and arms of Arenberg.[2] On 5 March 1576, Emperor Maximilian II raised his mother and her heirs to the rank of Princely Counts, thereby promoting them to the Council of Princes of the Imperial Diet.[3] Apart from the immediate princely county of Arenberg, the family owned extensive properties in the duchy of Brabant (the lordships of Vorselaar, Loenhout and Humbeek), the duchy of Luxembourg (the lordship of Mirwart and half of Neufchâteau) and the county of Holland (the barony of Zevenbergen and the lordships of Terschelling and Naaldwijk).[4]

At the age of ten, Charles of Arenberg was sent to the court of Albert V of Bavaria, where he would remain for three years. In 1566 he set out on a grand tour, visiting Paris, Lyon, Venice, Rome, Naples, Palermo, Malta, Florence and Strasbourg and studying law at the University of Bologna. He returned to the Netherlands shortly after the outbreak of the Dutch Revolt and the death of his father in the battle of Heiligerlee. His mother wanted him to stay neutral in the revolt and used her influence to have him sent on diplomatic missions. In 1570 he joined Archduchess Anna of Austria and her two brothers, the Archdukes Albert and Wenceslaus on their journey to the court of Philip II. From there, the king sent him on a mission to Charles IX of France to salute the birth of Marie Elisabeth of Valois. On his way back from a pilgrimage (1573) to Rome and Loreto, Charles of Arenberg accompanied the widowed Elisabeth of Austria from Nancy to the Imperial Court in Vienna (1575–1576). During his stay in Vienna Arenberg was raised to a princely county. In the meantime, the rebellious States of Holland had confiscated his estates in 1572. After a brief restitution in 1577, they were once again seized in 1579. In the process these properties suffered considerable damage.[5]

In August 1581, Alexander Farnese appointed Charles of Arenberg colonel of a regiment of German cavalry. He saw action during the Cologne War (1582–1584), notably in the Siege of Godesberg (1583), participated in the sieges of Antwerp (1585) and of Sluis (1587) and joined Farnese's campaign in France (1590).[6]

On 27 April 1586, Charles of Arenberg was awarded the Order of the Golden Fleece. In the same year, he made his entry in the Collateral Councils that advised the governor-general. Philip II appointed him a member of the Council of State and one of the heads of the Council of Finance. The following year, he was among the delegation that met with the envoys of Queen Elisabeth I at Bourbourg in 1587, in a feigned attempt to end hostilities between England and Spain. At the accession of the Archdukes Albert and Isabella, Arenberg saw his loyalty to the House of Habsburg rewarded. He was maintained as a member of the Council of State (1598) and was appointed a gentleman of the archducal Bedchamber (1599), lieutenant-general and admiral of the Netherlands and president of the Council of Admiralty (1599) and finally grand falconer of the Netherlands (1600).[7]

For the next few years, Charles of Arenberg acted as the Archduke's most prestigious ambassador. In 1598 he was among the delegation that went to Paris to witness the ratification of the Treaty of Vervins by Henry IV of France. He returned to the French Court two years later, to congratulate the king on his marriage with Marie de' Medici.[8] In June 1603 Charles of Arenberg was sent on an embassy to congratulate King James VI and I upon his accession to the English throne. On 4 October he had an audience with Anne of Denmark.[9] The mission was meant to pave the way for an end to the Anglo-Spanish War, but almost backfired when Arenberg was wrongfully accused of involvement in the Main and Bye Plots. The following year, he headed the archducal delegation that negotiated the Treaty of London.[10]

Increasingly suffering from gout, Charles of Arenberg thereafter withdrew from active politics. In 1607 he and his wife bought the domain at Enghien from Henry IV of France. He recuperated the expense by selling off the Dutch possessions that had been restored to him by the Twelve Years' Truce.[11] The lordships of Naaldwijk and Terschelling were among the goods that were sold. In order to make Enghien their principal seat, the Arenbergs rebuilt the castle and made many improvements to the gardens, with Robert Cecil's gardens at Theobalds House allegedly serving as an example. In the town of Enghien they founded a Capuchin monastery that would henceforth serve as the dynasty's necropolis.[12]

Charles of Arenberg was the founder of the third and present House of Arenberg. On 4 January 1587 he married Anne de Croÿ, the eldest daughter of Philippe III de Croÿ, 3rd duke of Aarschot. When his brother-in-law, Charles III of Croÿ, 5th Prince of Chimay, 4th duke of Aarschot, died without issue in 1612, most of his titles and estates passed to Anne and her descendants. They had 12 children:[13] Most of the current high nobility of Belgium descends from him, his descendance contains major noble families.
