abstract:Quadragesimo Anno (Latin for “In the 40th Year”) is an encyclical issued by Pope Pius XI on 15 May 1931, 40 years after Leo XIII's encyclical Rerum Novarum. Unlike Leo XIII, who addressed the condition of workers, Pius XI discusses the ethical implications of the social and economic order.
Another Jesuit, Oswald Nell-Breuning (1890-1991), who played a role similar to Liberatore in the drafting of QuadragesimoAnno (1931), is sometimes accused of sharing a corporatist view of society.
