Following a meeting by a commission convened by King Charles III on January 29, 1767, it was decided to expel members of the Society of Jesus, the Jesuits, from all lands belonging to the Spanish crown. The decision was made on the basis of the perceived threat of the Jesuits to royal authority. On April 7, 1767, the corregidor–the king’s representative–communicated the royal command to the public authorities in Bizkaia and the Jesuit residence in Bilbao, San Andrés college, was immediately occupied by law enforcement officers and there gathered Jesuits from Lekeitio, Urduña/Orduña, Vitoria-Gasteiz, and Logroño. On May 3 they boarded two waiting ships in the Olabeaga neighborhood that would transport them to Civitavecchia, outside Rome.
Among those expelled was Pedro de Calatayud, a member of the Bilbao order from Tafalla, Navarre, and the author of a controversial book some years previously in which he criticized traders, shipowners, and iron foundry owners in Bizkaia for their excessive greed and usury, even branding them “public sinners.” In retaliation, these business interests in Bizkaia began a campaign against him with the aim of getting the book banned or at least condemned by the Church. This campaign lasted some twenty years before, finally, in 1766 the work was indeed banned. Calatayud appealed against the ban, but the expulsion order brought an end to the matter. Calatayud died in Bologna in 1773.
