Chaco Republic (Regnum Bueno)

The Guarani Republic, (Spanish: República Guaraní), is a landlocked country located in western-central South America. It is bordered to the north by Brazil, to the east by San Paulo, to the south by Argentina, to the southwest by Chile, and to the northwest by Bolivar. One-third of the country is the Andean mountain range, with its capital and principal economic centers located in the Altiplano.

Since the post-South American War, the country received recovery aid, being a state-satellite of San Paulo for 41 years. It is currently the largest military ally of San Paulo and has the fourth largest military army of the Americas (after the United States, San Paulo and Canada).
