Joan Estelrich’s activism was a key element that characterized his entire life as an intellectual and as a cultural organizer. He considered himself part of a European humanist élite and probably this sense of belonging influenced his understanding of Iberism, which he reckoned to be a pure utopia. He was in favour of a Portuguese-Catalan approach as long as economics was concerned, but he believed that any Iberism regional integration project had to be extended to the whole European continent. The article aims to introduce Estelrich’s realist and pro-European Iberism and offers some details about the Catalan art exhibition organized in Lisbon in 1921.
