Well, this is the inset box from the previous map. Most of it is historic, the only difference being the different date of conquest of Uruguay, and of course, replace Meridian and UPSA by Spanish and Spain, respectively. The Guaraní Wars actually did happen, and in fact a joint Spanish-Portuguese (actually, Argentinian-Brazilian) army did quell the rebellion.
Actually, I'm thinking of changing the style on this one to serve for class use.
