Rerum Novarum. Papal
encyclical issued on 15 May 1891, ‘On the Condition of the Working Classes’. It represents the response of
Leo XIII to problems created by the Industrial Revolution, and formulates a doctrine of work, profit, industrial relationships, social justice, and the necessity of a proper wage. A principal aim was ‘to keep under all strife and all its causes’.
