History of Luxembourg: From Siegfried's rock to the heart of Europe: a thousand-year fortress that lost two-thirds of its land yet became a founding… Canonical: https://terralore.co/country/LUX/chronicle Updated: 2026-06-13 Founding: Count Siegfried acquires the rock of Lucilinburhuc — 963. Luxembourg traces its origin to the year 963, when Siegfried, a count of the Ardennes, obtained a rocky promontory above the valley of the Alzette on which a small fortified site called Lucilinburhuc, the 'little fortress', already stood. The castle Siegfried built on this Bock promontory is regarded as the birthplace of the city, the country and the nation, and the name of the stronghold became the name of the realm. From his descendants grew the County of Luxembourg, raised to a duchy in 1354, and the House of Luxembourg that supplied the Holy Roman Empire with several emperors. The rock's command of trade and military routes between western and central Europe made it one of the continent's strongest fortresses, fought over for nine centuries until its neutralisation and dismantling were ordered by the Treaty of London in 1867. Luxembourg's history is that of a tiny territory whose strategic rock made it one of Europe's most contested places. The story begins in 963, when Count Siegfried of the Ardennes acquired the promontory of Lucilinburhuc on the Alzette and raised the castle that gave the country its name. From his line sprang the House of Luxembourg, which in the fourteenth and fifteenth centuries gave the Holy Roman Empire emperors Henry VII, Charles IV and Sigismund. The rock grew into a fortress so formidable it was nicknamed the 'Gibraltar of the North', and for centuries it passed between Burgundian, Spanish, French and Austrian hands. Luxembourg was repeatedly partitioned: France took a slice at the Treaty of the Pyrenees in 1659; the Congress of Vienna in 1815 raised it to a Grand Duchy under the Dutch king while placing it in the German Confederation; the Treaty of London of 1839 handed the larger French-speaking half to the new kingdom of Belgium; and the Treaty of London of 1867, ending the Luxembourg Crisis between France and Prussia, guaranteed the country's perpetual neutrality and ordered the great fortress demolished. The crown separated from the Netherlands in 1890 under the Nassau-Weilburg dynasty. Twice occupied by Germany in the World Wars, Luxembourg abandoned neutrality after 1945 and became a founding member of Benelux, NATO, the European Coal and Steel Community and the European Union, its capital one of the three official seats of the EU.
