Have the boundaries of Argentina changed?

Yes, the boundaries of Argentina have changed over time, primarily due to historical conflicts, treaties, and territorial disputes. Significant changes occurred during the 19th century as Argentina consolidated its territory, particularly with the incorporation of regions such as Patagonia and parts of the Gran Chaco. Additionally, disputes with neighboring countries, such as Chile and Paraguay, have influenced Argentina's borders, although most of these issues have been resolved through diplomatic means. Overall, while the current boundaries have remained stable since the late 19th century, historical shifts have shaped the nation's territorial limits.
