The Riamese intervention in Gran Rugido (Spanish: Intervención riamese en Gran Rugido) also known as the Riamese-Rugidoense War (1861–1867) was an invasion of the Republic of Gran Rugido, launched in late 1862 by the Riamese Empire. It helped replace the republic with a monarchy, known as the Empire of Xalco, ruled by the tlatoani Cristóbal I.
