Cantacuzino: Byzantine survivors, Romanian patriots and Russian princes
One of the most interesting aspects of the high aristocracy in European history is its fluidity. In the centuries before the rise of nationalism, elites could and often did move from place to place and adapt to new scenarios with relative ease. On this site, we’ve seen examples of this already with the Scottish Hamiltons…
Lannoy: A Quintessentially Belgian Noble House
The new Grand Duchess of Luxembourg, born Countess Stéphanie de Lannoy, comes from an old noble family from the Low Countries. The House of Lannoy is one of the most distinguished noble houses in Belgium, yet nether of the two princely titles they held at different parts of their history—Sulmona and Rheina-Wolbeck—were located in Belgium.…
Nassau-Weilburg and Luxembourg: one of Europe’s oldest princely dynasties on one of its newest thrones
On 3 October 2025, Henri, Grand Duke of Luxembourg, abdicated his throne in favour of his eldest son, Crown Prince Guillaume. The Grand Duchy of Luxembourg as an independent sovereign state has only had its own ruling family since 1890, though the Duchy of Luxembourg itself (and before that the County) is far more ancient,…
Kent—From Saxon Kingdom to Royal Dukedom
Kent is one of the most familiar names for an English county—but also unique in that it is one of the few that are never appended ‘-shire’ when giving historic names. It is also said to be one of the oldest place names still in use in England, named by the Greeks as Kantion in…
Dukes of Castries: the Wealth of the Mediterranean comes to Versailles
In ancient times there was a road, the Via Domitia, built by the Romans to bring soldiers and trade across the Alps from Italy into southern Gaul, then south to Spain. Cities and towns along this route that hugged the Mediterranean prospered, and fortified positions held by noblemen kept trade safe, and of course provided…
Dukes of Cleveland: Two FitzRoys and Several Vanes
One of the least known dukedoms in the peerages of Great Britain is that of Cleveland. After starting off as a title for one of the most famous duchesses in Europe, Barbara Villiers, the second and third dukes, Charles and William FitzRoy, were very rich but unremarkable. Their successors in the Vane family managed to…
The Leslies: Just one Duke of Rothes but many generals in Scotland, Russia and Austria
‘You know nothing, Jon Snow’, is perhaps a fitting introduction to the family history of Rose Leslie, an actress famous for playing Ygritte the Wildling in Game of Thrones. Snow did in fact know nothing about his own true ancestry in the story, but he also did not know that his real-life counterpart, Kit Harington,…
The MacCarthys—Irish kings to princes … to dukes?
Ireland did not have dukes and princes created by emperors or kings in the manner of other European kingdoms in the medieval and early modern ages. There were a few dukedoms (Ormond, Leinster, Abercorn), but these were all created for Anglo-Irish families who had emigrated to the Emerald Isle at some point after its conquest…
Dukes of Medina Sidonia: Virtual kings of Andalusia
One of the wealthiest and most powerful aristocratic families in Spain are the dukes of Medina Sidonia. With their base in the Andalusian seaport town of Sanlúcar de Barrameda, huge estates across the south of Spain, and the oldest extant dukedom in the Kingdom, they dominate much of Spanish history from the fifteenth century to…
Eulenburg and Bülow princes: two scandals that shook the Prussian court
The court of Kaiser Wilhelm II is remembered for its excessive militarism—the Prussian sabre rattling that encouraged the Austrian emperor to send such a strong ultimatum to the Serbs in July 1914 that made World War I inevitable—an excess that ultimately brought about the demise of both monarchies and the dukes and princes that supported…
