Thousands of people took to the streets across Spain on March 14, 2026, under the banner "No to war," demanding an end to military escalation against Iran and calling for a halt to the conflict in the Middle East. The largest gathering took place in Madrid, where approximately 5,000 people assembled to demand an end to the war and to keep attention on Gaza, according to Notícias ao Minuto. Parallel demonstrations were held in other Spanish cities, while hundreds of protesters also gathered in Lisbon, Portugal, according to reporting by Jornal Expresso and JN. In Santander, dozens of demonstrators turned out despite heavy, unrelenting rain, according to eldiario.es.
In Lisbon, protesters directed their demands specifically against what they described as threats from the United States and Israel toward Iran, calling for an end to military escalation, according to Jornal Expresso. Demonstrators in the Portuguese capital marched under the slogan "Peace yes, war no," according to JN. The Lisbon protests addressed the broader conflict in the Middle East alongside the specific situation regarding Iran. Across both countries, the demonstrations drew a cross-section of civil society groups united by opposition to military action.
The March 14, 2026, protests echoed the historic global anti-war demonstrations of 2003, which were held in coordination worldwide against the imminent invasion of Iraq by the United States and its allies, according to eldiario.es. Those 2003 protests were among the first truly global coordinated demonstrations in history, according to the same source. The current wave of protests came 23 years after that earlier movement, according to eldiario.es. A second United States aircraft carrier had appeared to be heading toward the Middle East in February 2026 as Washington increased pressure on Iran, according to web search results.
The organizers and participants framed the 2026 demonstrations as a direct continuation of the 2003 anti-war tradition, invoking the same core slogan across both Spain and Portugal. The protests in Madrid and other Spanish cities were described by El Confidencial and 20 minutos as drawing thousands of participants in total. The No to war slogan served as the unifying call across all locations, from large urban centers to smaller cities such as Santander. The demonstrations in both Iberian countries reflected shared concern over a potential military confrontation involving Iran, as well as the ongoing situation in Gaza.
