The history of Luxembourg for the exam: the essential timeline
From Siegfried and the Lucilinburhuc of 963 to the euro and Schengen: the dates, figures and turning points the official syllabus asks you to know.
Contents
Ten questions out of forty deal with the history of Luxembourg and European integration. That is a quarter of the marks, and it is the subject where a good timeline pays off fastest: most questions turn on clearly identified dates, names and turning points.
This article follows the official syllabus: from the origins to the State, from industrialisation to 1945, then from 1945 to today.
From the origins to the State
963 — Siegfried and the Lucilinburhuc
Count Siegfried acquires the Bock promontory through an exchange with the Abbey of St Maximin in Trier. The name of the fortress, "Lucilinburhuc", means "little castle". From it derives "Luxembourg", which today names both the capital and the country.
This date is regarded as the founding act of Luxembourg. The town grew up around the fortress built on Roman remains.
963–1443 — From county to duchy
Luxembourg is a county until 1354, then raised to a duchy. In the fourteenth century, the House of Luxembourg reaches its European peak, giving several emperors to the Holy Roman Empire.
In 1443 the duchy passes under Burgundian rule. There follows a long period during which the territory changes hands among the great powers: Spanish, French, Austrian.
1815 — The Congress of Vienna and the Grand Duchy
The Congress of Vienna raises Luxembourg to a Grand Duchy and entrusts it to the King of the Netherlands, who becomes Grand Duke in a personal capacity. The territory is simultaneously integrated into the German Confederation, with a Prussian garrison in the fortress.
A distinction to lock in: 1815 = creation of the Grand Duchy. 1839 = Treaty of London, present-day borders. These two dates are systematically offered together in multiple-choice questions.
1839 — The Treaty of London
The Treaty of London divides the territory: the French-speaking part (today's Belgian province of Luxembourg) is ceded to Belgium, while the German-speaking part keeps the name of Grand Duchy. This creates today's borders and starts the building of a genuinely distinct State.
1867 — The Treaty of London and neutrality
Following the "Luxembourg Crisis", a second Treaty of London confirms the country's independence, imposes its perpetual neutrality and orders the dismantling of the fortress. The remains of those fortifications — the Bock casemates — are today a World Heritage site.
1890 — The Nassau-Weilburg dynasty
On the death of William III, the Dutch crown passes to his daughter Wilhelmina, but because Luxembourg's succession law then required male succession, the Grand Duchy passes to Adolphe of Nassau-Weilburg. The personal union with the Netherlands ends: Luxembourg has its own dynasty.
From industrialisation to 1945
Industrialisation and steel
The discovery of iron ore in the south of the country — the Minette — turns an agricultural country into a steel power. The mining basin attracts massive foreign labour, notably Italian and later Portuguese. Railways, the southern towns and emerging social legislation accompany this shift.
Note the double migratory movement: Luxembourg is first a country of emigration in the nineteenth century, before becoming a country of immigration.
1914–1918 — The First World War
Despite its neutrality, Luxembourg is occupied by Germany from August 1914. The country keeps its institutions, but occupation and shortages weigh heavily on the population and weaken the monarchy.
1919 — Political crisis and constitutional renewal
1919 is a major turning point:
- Grand Duchess Marie-Adélaïde abdicates in favour of her sister Charlotte;
- a referendum confirms the monarchy;
- universal suffrage is introduced, including for women.
1921 — The Belgium–Luxembourg Economic Union
The UEBL ties Luxembourg to Belgium through a monetary and customs union. It is the country's first major experiment in economic integration, and a forerunner of its later European commitment.
The 1930s — The "muzzle law"
In 1937, a bill seeking to ban the communist party — nicknamed the muzzle law — is rejected by referendum. The episode is regularly cited as a marker of the country's attachment to political freedoms.
1940–1945 — The Second World War
This period is covered in detail in Luxembourg during the two world wars. The markers to know:
- May 1940: German invasion; Grand Duchess Charlotte and the government go into exile;
- forced Germanisation: French banned, enrolment in Nazi organisations;
- October 1941: in the census (Personenstandsaufnahme), the population answers "Luxembourgish" en masse to the questions on language, nationality and ethnicity;
- August 1942: the announcement of compulsory conscription into the Wehrmacht triggers a general strike, harshly repressed;
- persecution of the Jewish population and deportations;
- 10 September 1944: liberation of the capital;
- winter 1944-1945: the Battle of the Bulge devastates the north of the country.
From 1945 to today
The end of neutrality
The war demonstrated that declared neutrality protects nothing. Luxembourg abandons that status and commits firmly to international cooperation:
- 1944-1948: creation of Benelux with Belgium and the Netherlands;
- 1945: founding member of the United Nations;
- 1949: founding member of NATO;
- 1949: founding member of the Council of Europe;
- Marshall Plan: American aid for reconstruction.
Never confuse the Council of Europe (human rights, European Convention, Strasbourg court) with the European Union (27 states, Charter of Fundamental Rights, Court of Justice in Luxembourg). It is one of the most frequent traps in the exam.
European integration
- 1951: Treaty of Paris creating the European Coal and Steel Community (ECSC). Luxembourg is a founding member and hosts the High Authority.
- 1957: Treaties of Rome, creating the EEC and Euratom.
- 1985: signature of the Schengen Agreements, in the Luxembourg village of the same name, on the border with France and Germany.
- 1992: Maastricht Treaty, birth of the European Union and the path to the single currency.
- 1997: Treaty of Amsterdam. 2007: Treaty of Lisbon.
- 2002: euro coins and notes enter circulation.
Details in Luxembourg and European integration.
The steel crisis and economic transformation
From the 1970s, the steel industry collapses. The country reorients its economy towards financial services, then towards technology and European activities. That transition, managed through consultation between the State, employers and unions, explains the country's present economic structure.
Migration and society
Immigration transforms the demography: after the Italians, a large Portuguese community settles from the 1960s-1970s, followed by other European and international waves. Luxembourg becomes one of the European countries with the highest share of foreign residents — which is precisely why a civic integration pathway such as "Vivre ensemble" exists.
