Pope Leo XIV addresses Spanish parliament, advocating for migrants' rights and ethical AI oversight.

Pope Leo XIV made history on June 8, 2026, becoming the first pope ever to address the Spanish parliament. Speaking before a joint session of the Cortes Generales in Madrid, he demanded respect for migrants' rights and called for strict oversight of AI weapons systems. Lawmakers gave him a minutes-long standing ovation AP.
The speech marked a striking moment for a largely secular country. While roughly 60–70% of Spaniards identify as Catholic, regular church attendance is at historic lows Interlochen Public Radio. Yet both the ruling Socialists and the conservative opposition rose to applaud the American-born pope.
Leo told parliament that a nation's true greatness is measured by how it treats its weakest members. "The moral greatness of a nation is manifested, above all, in its capacity to accompany, protect and love those lives that are most fragile," he said Interlochen Public Radio. He urged Spain and the European Union to move toward what he called a "hospitality-first" approach to migration law.
The pope is scheduled to end his seven-day Spain tour in the Canary Islands, a major entry point for migrants crossing the Atlantic from Africa Anadolu Agency. There he plans to meet migrants directly at the port of ArguineguÃn. The visit is seen as a deliberate act of pressure on both Madrid and Brussels.

Historian Massimo Faggioli described what he called a "rock star effect" — politicians using Leo's moral authority to project unity in a fractured country France 24.

The parliament speech built on Leo's first encyclical, *Magnifica Humanitas*, released May 25. The 43,000-word document issued a landmark apology for the Church's role in slavery and called for the "disarming" of artificial intelligence Reuters. It set the tone for his entire Spain trip.
Leo arrived in Madrid on June 6, welcomed by King Felipe VI and Queen Letizia at the Royal Palace. In his arrival speech, he urged Spaniards to stop "fanning the flames of polarization" PBS.
