Paraguay and the Río de la Plata region · Animated schematic fronts

Paraguayan War

Paraguay fought Brazil, Argentina and Uruguay. The war devastated Paraguay and caused very high mortality through fighting, disease and hunger; precise population losses remain a subject of historical debate.

This war had no continuous front. The line is a schematic limit of advance and operations: it summarises campaigns and is not a trench line or an administrative border. The coloured areas are operational sides, not evidence of contiguous occupation; in-between frames are interpolated and closing edges are graphic. The line follows the main armies along the Paraná and Paraguay rivers; the Paraguayan invasion of Mato Grosso is not shown.
