Echoes of 2003 are reverberating through Barcelona. As new conflicts flare in the Middle East, the city is reflecting on a moment when its streets swelled with an unprecedented 1.3 million people to protest the impending Iraq War. The memory of balconies draped in white peace sheets and windows bearing ‘stop the missile’ logos is prompting a pressing question: could such a monumental display of public will happen again?

The catalyst for this introspection is the current geopolitical climate and, closer to home, a notable shift in political rhetoric. Spanish Prime Minister Pedro Sánchez recently adopted the famous slogan, declaring “no to war” in response to rising tensions involving Iran. This stance has stirred memories for many who marched two decades ago, but it also highlights the stark contrast between then and now.

A Different Political Landscape

In 2003, the protest was a direct challenge to Spain’s own government. Prime Minister José María Aznar had aligned the country with the US-led coalition, a decision that created immense social friction and fuelled the demonstration on 15 February 2003, one of many global protests against the war that day.

Today, the situation is inverted. “The context is different because the government is the anti-Trump and anti-war reference point,” explains Dani Gómez-Olivé, who was a spokesperson for Aturem la Guerra (Let’s Stop the War), the platform that organised the 2003 mobilisation. According to reporting in El País, Gómez-Olivé notes that Sánchez has skilfully tapped into a deep-rooted pacifist sentiment.

“The president himself has decided to lead the denunciation of what we were saying 20 years ago: that it is, as it was then, an illegal war because preventative wars do not exist in international law,” he says. “He has been surprisingly successful in leading and getting other European governments to back down from having such an uncritical voice towards the US.”

The Anatomy of a Movement

The 2003 protest was not a spontaneous event. It was the culmination of two years of smaller demonstrations and the convergence of various social movements. Pacifists, anti-globalisation activists like Gómez-Olivé and a young Ada Colau, and the city’s powerful squatter (*okupa*) movement all found a home under the Aturem la Guerra banner.

The platform achieved an unprecedented level of cross-societal support, uniting all political parties (except Aznar’s Partido Popular), trade unions, and neighbourhood associations. “You could see deputies from [the centre-right Catalan party] CiU and squatters in the same meeting,” Gómez-Olivé recalls. A critical factor, he adds, was the involvement of the education sector, which brought the anti-war message directly into family homes and helped structure the movement.

Mònica Marco, who marched in 2003, remembers the sheer scale of the day. “There were so, so many people. Whole families, immigrants,” she says, recalling how spontaneous applause would ripple through the crowd. The protest was so dense it was more of a static rally than a march. “The manifesto was read five or six times. Those who read it almost knew it by heart,” Gómez-Olivé jokes.

A Deep-Rooted Pacifist Tradition

Barcelona’s powerful response built on a long tradition of peace activism, from protests against Spain’s entry into NATO to the conscientious objector movement. Indeed, this sentiment remains potent. A recent survey by the research firm 40dB found that opposition to the current conflict is 71% in Catalonia, higher than the Spanish average of 68%. This anti-war feeling visibly weaves into the city’s fabric, evident in recent demonstrations against US and Israeli military action, and anti-war street art like a recently vandalised Tvboy mural in Gràcia.

The city’s history, marked by events like the Spanish Civil War, has left an indelible mark on its collective memory. This history is physically revealed through discoveries like the Civil War shelter found under a Hostafrancs street.

The 2003 protest was so significant it even drew a comment from former US President George Bush Sr., who remarked that US security policy could not depend on “whether many or few people take to the streets of Barcelona.” Gómez-Olivé recalls the comment as “a bit mind-blowing.”

Could History Repeat Itself?

Despite the enduring pacifist culture, those involved are divided on whether a similar mobilisation is possible. Mònica Marco is sceptical. “I don’t think so,” she reflects. “Bush seemed the worst, but having a fascist in the White House now has made him look good.” She adds, “We may be angrier, but the government’s response is very different. People are less mobilised.”

Gómez-Olivé believes the potential is there, but that the target is missing. If a government aligned with Donald Trump were in power at La Moncloa, he suggests, a protest on a similar scale could be achieved. “I want to think so. The fertile ground exists,” he states. “The culture of peace is widespread.”

For now, with the Spanish government itself leading the anti-war chorus, the dynamic has fundamentally changed. The streets of Barcelona remain a potent symbol of peace activism, but the unique political storm that gathered 1.3 million people in 2003 has, for the moment, passed.
