National Day of Catalonia

Spain Β· Date: Friday, September 11, 2026

The National Day of Catalonia, or La Diada, commemorates the fall of Barcelona in 1714 during the War of the Spanish Succession. It is a day of political demonstrations, cultural events, and Catalan pride.

Origin & history

The National Day of Catalonia, known as La Diada Nacional de Catalunya, commemorates the fall of Barcelona on September 11, 1714, during the War of the Spanish Succession. After a 14-month siege, the city surrendered to the Bourbon forces of King Philip V, leading to the abolition of Catalan institutions and the imposition of centralizing decrees known as the Nueva Planta. This event marked the end of Catalonia's historical rights and self-governance. The holiday was first officially celebrated in 1886 but was suppressed under Francisco Franco's dictatorship. Following Spain's transition to democracy, the Catalan government restored the day in 1980 as a symbol of resistance and national identity.

Customs & traditions

La Diada is marked by a blend of political activism, cultural festivities, and family gatherings. The day typically begins with official ceremonies, including a floral offering at the monument to Rafael Casanova, a Catalan leader during the 1714 siege. Many Catalans participate in massive demonstrations advocating for independence or greater autonomy, with Barcelona's streets filled with protesters waving esteladas (Catalan independence flags). Cultural events include open days at the Catalan government palace, concerts of traditional music like sardanas, and human towers known as castells. Food plays a role, with families enjoying local specialties such as pa amb tomΓ quet (bread with tomato), butifarra (sausage), and cava. The day is also a public holiday, allowing for a mix of reflection and celebration.

Why it is celebrated

For many Catalans, La Diada represents a day of national identity, remembrance, and political expression. It serves as a powerful symbol of Catalan resilience and the desire for self-determination, particularly in the context of ongoing debates over independence from Spain. The holiday is both a historical commemoration and a platform for modern political aspirations, uniting Catalans in their shared heritage and future goals.
