Oberhaupt Charles III (seit 8 Sep 2022)

Verwandtschaft Descends from both roots: from Queen Victoria directly, and from Christian IX via Alexandra of Denmark (daughter of Christian IX) and Prince Philip.

Vermögen ≈ $0.77–1.1 billion (estimate) · Sunday Times Rich List 2024 / CEOWORLD 2025

Fate“mediatised” in 1806 — sovereignty lost, rank & equality of birth retained

Bis heute mostly continuing as princely/comital families with castles & forests

The rulebook

The Golden Bull · 1356

FoundationCharles IV fixed the seven prince-electors, the procedure for electing the king, the indivisibility of the electoral lands and succession by primogeniture — in effect the constitution of the Empire.

Continuing effectFor 450 years it defined who even belonged to the innermost circle of power. The electoral houses are exactly the ones that later gained royal crowns: Brandenburg → Prussia, Saxony, Palatinate/Bavaria, Hanover.

The ancient treaties

Mutual succession pacts & house treaties

FoundationTreaties between houses: if one line dies out, the allied one inherits. Plus house treaties such as the Treaty of Pavia (1329, Wittelsbach) or the Wettin agreements from 1485 onwards.

Continuing effectThese treaties bundle inheritance claims across centuries and borders — they are the true “foundation of the Uradel claim”.

Concretely today: the Saxon succession dispute explicitly invokes the mutual succession pact of 1485 to determine the head of the “whole House of Wettin”. And the inheritance treaties of the Princes of Hohenzollern-Hechingen/-Sigmaringen with Prussia (1695/1707) meant that their lands passed to Prussia in 1850.

The accumulation engine

Primogeniture · Dispositio Achillea 1473

FoundationAlbrecht Achilles laid down indivisibility + primogeniture for the Hohenzollerns: one heir gets (almost) everything; the property is never divided.

Continuing effectPrecisely this principle keeps wealth from fragmenting across generations. It is the quiet reason family property stays together for 500 years instead of evaporating.

House law in court

Equality of birth & inheritance contract

FoundationHouse laws demanded marriage “befitting one's rank”; whoever marries beneath their rank loses the inheritance via the equal-birth clause in the inheritance contract.

Continuing effect & limitThe Federal Constitutional Court (22 Mar 2004, “Hohenzollern”, 1 BvR 2248/01) ruled: such clauses may not exert “unreasonable pressure” on the freedom to marry (Art. 6 of the Basic Law). So the old house norms live on in private law — the constitutional state limits them.

In sovereign Liechtenstein, by contrast, the house law of 1993 is valid constitutional law — there, house law still determines the head of state today.

The wealth vehicles

Fideicommissum → court chamber & foundation

FoundationThe fideicommissum bound family property to the line, indivisible and unsellable — abolished in 1919, wound up by ~1938.

Continuing effectIn its place came the court chamber, the corporate group and the family foundation: for instance the Hofkammer of the House of Württemberg, the Unternehmensgruppe Fürst von Hohenzollern, the Esterházy private foundations. Forests, palaces, wineries and real estate are bundled to last for generations.

This is the actual power base today — not thrones, but land + capital in durable legal entities.

Power as litigation

Restitution & property

FoundationAfter 1918 / 1945 / 1990 came endless proceedings over palaces, art and compensation.

Continuing effectSettlements with Saxony/Wettin (2014), Saxe-Coburg-Gotha, Mecklenburg. The Hohenzollerns negotiated from 2014 onwards and in 2023 withdrew two multi-million lawsuits (the Potsdam administrative court closed the proceedings); in 2025 the disputed art objects were transferred into a charitable foundation.

The lesson: “power in the background” appears concretely as disputes over land registers and files — justiciable and open to inspection, not hidden.

The invisible web

Marriage · orders · patronage

FoundationEndogamous marriage policy links the houses across Europe into a “cousinhood” — kinship as infrastructure, not as coincidence.

Continuing effectOrders of knighthood with real standing: the Order of Malta is a subject of international law in its own right (diplomatic relations with around 110 states, UN observer); alongside it the Order of St John and the Order of the Golden Fleece (grand masters: Habsburg and the Spanish Bourbons, respectively).

Privately, the nobility associations also maintain their own “law of nobility” (the Adelsrechtsausschuss; the Genealogisches Handbuch / “Gotha”) — with no state validity at all, purely as a self-administered order.

The state's framework

Art. 109 WRV / Art. 123 GG

FoundationWeimar 1919 abolished the nobility as an estate: titles became mere parts of the name, with no privileges. Carried over into the Basic Law.

Continuing effect & limitReintroducing the monarchy is ruled out by Art. 20 & 28 of the Basic Law. What remains is private law — the houses organise themselves as associations, foundations or limited companies.

The framework is openly visible; nothing about it is secret. That is the central point of this entire section.
