This article describes and documents the facts and most notable experiences in labour education on the Balearic Islands from the 1868 revolution until the end of the Civil War. We highlight the republican and socialist experiences on Mallorca and Ibiza and describe the five secular schools that were opened on the island of Menorca at different points in time. Although Ferrer i Guardia’s influence on the emergence and consolidation of these labour initiatives is clear, it is also evident that the free-thinking movement, secularism and republican initiatives and all kinds of progressive communities worked to secularise society before the experience of the Modern School.
