Nazi Annexation & National Resistance

1795 - 1940

French Revolutionary armies occupied Luxembourg in 1795, ending the fortress city's old regime and inaugurating a century of transformation. The Dancing Procession, banned in 1786 by Emperor Joseph II, was revived in 1802 — its first revival after ecclesiastical suppression, foreshadowing the post-WWII revival that would inscribe it with national-resistance meaning. The Treaty of London (1867) granted Luxembourg independence and neutrality, and the fortress — that "Gibraltar of the North" — was demolished stone by stone between 1867 and 1883, opening the city to the modern world. From the 1850s, the red earth of the Minett region drew steel industrialists and immigrant workers. Esch-sur-Alzette grew from 810 inhabitants (1821) to an industrial powerhouse; Italians arrived from the 1890s, establishing their own theatre company and cultural associations. By 1910, immigrants constituted 15.3% of the population. The Centre de Documentation sur les Migrations Humaines (CDMH) in Dudelange, housed in the former Gare-Usines since 1993, documents this story. Meanwhile, the Éimaischen — the Easter Monday potters' market where Péckvillercher (clay cuckoo whistles) are sold in Luxembourg City's old quarter and Nospelt — was first documented in 1827, preserving a craft-seasonal rhythm where Easter's Christian calendar intersects with spring renewal.

1945 - 1990

Post-war Luxembourg abandoned neutrality for active European integration, signing the Treaty of Brussels (1948) and becoming a founding member of NATO, the European Coal and Steel Community, and the European Economic Community. European institutions settled in Luxembourg City, making it one of the three capitals of the European Union. On the Moselle, the village of Schengen gave its name to the 1985 agreement that would dismantle internal European borders — signed aboard the MS Princess Marie-Astrid near the Luxembourg-France-Germany tri-point on 14 June 1985. The National Day (Lëtzebuerger Nationalfeierdag) crystallized as a civic ritual: in 1961, the public celebration was shifted from the sovereign's actual birthday to the fixed date of 23 June, creating a midsummer festival anchored by the Fakelzuch (torchlight procession) on 22 June evening and the Te Deum at the cathedral. The Gëlle Fra (Golden Lady) monument on Constitution Square — erected in 1923, dismantled by the Nazis, and restored after the war — became the focal point for National Day ceremonies, its gilded angel of peace holding a laurel wreath over a city that had chosen democracy and multilingualism over annexation.

1443 - 1795

The Burgundian conquest of 1443 began three and a half centuries of foreign rule that remade Luxembourg as a fortress city and a Marian pilgrimage center. Spanish, French (under Vauban), and Austrian engineers transformed the Bock promontory into the "Gibraltar of the North" — an underground warren of casemates and tunnels that you can still walk today, carved directly into the living rock. The fortress made Luxembourg a strategic prize; its eventual demolition in 1867 would make it an independent neutral state. The casemates and remaining bastions are a UNESCO World Heritage Site since 1994. In 1624, during a plague epidemic, the Jesuit Father Jacques Brocquart commissioned a wooden statue of the Virgin Mary that quickly attracted pilgrims. The devotion was institutionalized by political decree: Our Lady was declared patron of Luxembourg City (1666) and the Duchy (1678) under the title Consolatrix Afflictorum — Consoler of the Afflicted. The annual Octave (Oktav) pilgrimage that grew around this statue, still centered at Notre-Dame Cathedral, became the template for how a Counter-Reformation creation could absorb national, political, and popular meanings far beyond its founding purpose — culminating in the Grand Ducal family's participation in the closing procession today. The Church banned the Dancing Procession in 1786 (Emperor Joseph II), revealing internal tension between popular ritual form and hierarchical orthodoxy.

From 1990

Contemporary Luxembourg is a multicultural society where 47.2% of residents are foreign nationals, with the Portuguese community alone constituting approximately 15% of the population. Portuguese festival practices — especially the Santos Populares (Popular Saints' festivals) in June, centered on Santo António on 13 June — now appear in Luxembourg's festival calendar, particularly in Esch-sur-Alzette and Schifflange, running parallel to and sometimes overlapping with the National Day celebrations on 23 June. The Centro Social e Cultural Português and folk groups like the Grupo Folclórico Mocidade Portuguesa do Luxemburgo (founded 1982) sustain these traditions across generations, though Portuguese community sources are underrepresented in official French/Luxembourgish-language documentation. Heritage recognition has reshaped how Luxembourg reads its own past. The Dancing Procession of Echternach was inscribed on UNESCO's Representative List of the Intangible Cultural Heritage of Humanity in 2010; the City of Luxembourg's old quarters and fortifications have been a UNESCO World Heritage Site since 1994; the Minett region was designated a UNESCO Biosphere Reserve in 2020; and Esch-sur-Alzette was a European Capital of Culture in 2022. At Belval, the former blast furnaces of the ARBED steelworks have been transformed into the Cité des Sciences, housing the University of Luxembourg — a material symbol of the post-industrial, knowledge-economy future built on the industrial past. Buergbrennen still burns every Buergsonndeg across the country, the Éimaischen still fills the old quarter with cuckoo whistles every Easter Monday, and the Schueberfouer still opens every August — each tradition a living thread connecting today's multicultural Luxembourg to the Celtic oppidum, the Roman road, and Willibrord's abbey.
