History

Historical Context

Amid rapid industrialisation in late-19th-century Europe, Pope Leo XIII issued Rerum Novarum on 15 May 1891, the Church’s first formal stance on workers’ rights and private property. That encyclical launched a tradition of social teaching echoed in later papal documents and now underpins the 2026 Vatican commission addressing AI ethics and seeks to guide AI regulation worldwide.
