Argentine irredentism

Argentine irredentism refers to the idea that Argentina has suffered large territorial losses early in the 19th century to neighboring countries, and that it must strive to regain control of them, forming "Great Argentina", envisioned with the same borders as the Viceroyalty of the Río de la Plata.^[1][2] This idea surged in popularity in the late 19th century, and peaked in influence in the late 1940s and early 1950s.^[3] All of these claims have been abandoned by Argentina, save for the Falkland Islands sovereignty dispute.

It is also known as "nostalgic nationalism" and "territorial nationalism" (a term coined by former Argentine diplomat Carlos Escude) to emphasize the fact that, unlike other forms of nationalism, it is not based on race, language, or culture, but geography and history.^[4]
