World Wars, Occupation & Heritage Revival

1830 - 1914

The Belgian nation-state made French its sole official language, and Brussels — historically Dutch-speaking — underwent rapid francization. Proficiency in French among Dutch-speakers increased spectacularly after 1880; French became the language of social advancement, and speaking Dutch carried a stigma. The covering of the Senne (1867-1871) under Mayor Jules Anspach addressed genuine sanitation crises but also displaced working-class neighborhoods, buried the river that gave Brussels its name, and replaced organic medieval topography with imposed Haussmann-esque boulevards. Leopold II drove monumental projects that reshaped Brussels — the Parc du Cinquantenaire/Jubelpark (built for the 1880 National Exhibition celebrating 50 years of independence, which included colonial displays), the Royal Palace expansions, the Royal Galleries of Saint-Hubert — funded substantially by revenues from the Congo Free State, his personal colonial domain. The 1897 Colonial Exhibition in Tervuren displayed Congolese people in a 'human zoo'; seven died. Art Nouveau, Brussels' architectural signature, also flowered in this era — but the working-class Brusselian and Marollien culture that had its roots in the guild era was being steadily erased by francization and urban modernization.

1958 - 1989

Since 1958, Brussels has been the administrative capital of what became the European Union — but the EU institutional presence is only one thread. Simultaneously, Belgium's linguistic frontier hardened: the language laws of 1962-1963 fixed Brussels as an officially bilingual enclave of 19 municipalities, abolished language censuses, and ended the 'freedom of the head of household' in education. The Berlaymont building rose as the Commission's headquarters, but the Marolles/Marollen district fought its own battle: the 1969 'Battle of the Marolles' saw working-class residents resist demolition of their neighborhood, continuing the district's tradition of resistance to imposed modernization that began with the Palace of Justice's construction. The zwanze (zwans) — a form of ironic, self-deprecating folk humor rooted in working-class oral tradition — survived in the Marolles, though the Marollien dialect that carried it was rapidly declining. French dominated public festival narration, but the traditions themselves — Ommegang, Meyboom, Manneken Pis dressing — all originated in a Dutch-language guild culture that francization had obscured.

1794 - 1830

French Revolutionary forces occupied Brussels in 1794 and systematically dismantled the guild-era civic order. The Nine Nations were suppressed in 1795; their archives and furniture were sold at public auction on the Grand-Place in August 1796, creating a massive gap in the documentary record for Brussels' festival history. Under the brief Dutch Kingdom (1815-1830), William I imposed Dutch as the official language — a policy that antagonized the French-speaking elite who had flourished under French rule. The Belgian Revolution of 1830 was, in part, this elite's rejection of Dutch-language governance. La Monnaie/De Munt became the revolution's stage: the opera 'La Muette de Portici' reportedly sparked the uprising on 25 August 1830. The revolution created a centralized, unilingual French-speaking state — and the francization of Brussels, already underway, accelerated dramatically.

From 1989

The Brussels-Capital Region was created in 1989 as Belgium's third federal region — officially bilingual in French and Dutch, though French is the majority language and lingua franca (77% of households). The traditional festival calendar — Ommegang (July, reenacting 1549), Meyboom (9 August, since at least 1308), Manneken Pis dressing (monthly, since 1616) — continues but is now framed more as heritage tourism than as living civic ritual. The Flower Carpet, created in 1971 by landscape architect Etienne Stautemans 'in an effort to advertise his work,' is timed to the Assumption weekend (15 August) but has no documented chain of ritual transmission — it is a modern tradition that activates a heritage site, not a surviving ritual. The Zinneke Parade, launched in 2000 during Brussels' turn as European Capital of Culture, represents a new model: 100% human-powered, involving workshops across all 19 municipalities and over 180 nationalities, named after the 'zinneke' (stray dog/mutt — a term of hybrid identity). Meanwhile, Moroccan, Turkish, and Congolese diaspora communities maintain their own festival calendars — Ramadan, Eid, Nowruz, Couleur Café — that are publicly visible in neighborhoods like Anderlecht, Molenbeek, and Matonge but remain absent from the official heritage inventory. The Brussels intangible heritage inventory added 'zwanze' in 2021 and 'Brussels Pride' in 2024, but no Muslim or African diaspora tradition has yet been recognized. Today you can read this layered city: stand on the Grand-Place atop the buried Senne, watch the Ommegang's imperial reenactment pass through streets that once hosted a religious circumambulation, and hear French, Dutch, Arabic, and Lingala spoken within blocks of each other.
