However, the concept is by far not an invention of the EU, but has a long tradition and experienced an evolution which was to a large extent parallel to the evolution of political sciences.
The word subsidiarity is derived from the Latin term subsidiarius and has its origins in Catholic social teaching. It mainly claims that government should carry out only those activities which exceed the capacity of individuals or private groups acting separately. The autonomy and dignity of the human individual is thus the central value of the principle, wherefore all other forms of society (e.g. family, state, international order) should be in the service of the human being. Without going further into detail, it seems appropriate to mention that it was elaborated in the encyclical Rerum Novarum of 1891 by Pope Leo XIII, as an attempt to articulate an intermediate option between capitalism on the one hand and the different forms of communism, which are characterized by the subordination of the person to the state, on the other.
