THE REFUGEE ISSUE has deep historical roots that go back to the 14th century. The Black Death killed up to half the population of Europe, but it led to a concentration of efforts to make childbearing safer, which, in due course, gave rise to the first hints of the population explosion to follow.
In the 16th century Europeans began traveling all over the world, and it wasn’t long before they started settling abroad. This colonization process wasn’t prompted merely by a spirit of adventure and the quest for gold, silver and other precious commodities but by the need for Europe’s growing population to find jobs. The trend intensified until the mid-20th century. The whole of the Americas and Australasia, parts of South Asia and sub-Saharan Africa were thus colonized. Argentina’s population doubled within 20 years, thanks mostly to Italian and Spanish immigrants, including the parents of Pope Francis.
