One of the apostolic fields in which the Society of Jesus was involved since its foundation in 1540 was the missiones ad gentes missions among non-Christians, which produced a constant flow of European missionaries to other continents. Specifically, the Jesuit provinces of Spain sent many missionaries beyond their borders, creating administrative units that were initially dependent on the metropolis and later became autonomous Jesuit territories. There are many partial studies of many of the realities related to the Jesuit missions; We now intend to take a brief historical overview to illustrate this centrifugal trend in Spain within the Jesuit sphere, both in the old Society (before its suppression by Pope Clement XIV in 1773) and in the contemporary one (since its restoration by Pope Pius VII in 1814). To this end, we will briefly review demographic and geographical data, which provide overall figures and territorial configurations throughout the history of the Society of Jesus.
