The Ryukyu War (1502-1504) was a minor engagement between the Fusahito Theocracy and the Ryukyu Kingdom, the first engagement between the Theocracy and any other state since its creation in 1472. The war was part of a larger campaign by the First Fusahito Emperor to stamp out the slave trade in East Asia, a direct result of the failure of the Kingdom to respond to Fusahito demands to stop the trade.
Troops from the Theocracy saw action of numerous islands, with fierce resistance met throughout the archipelago, particularly on the island of Amami Oshima, where many soldiers are cut down whilst landing on the beaches. The war was particularly more bloody than was predicted by the Emperor's advisers, but eventually saw an Imperial victory with troops from the Theocracy annexing the island of Amami Oshima (around one fifth of the land under Ryukyu control). All of the Fusahito aims were achieved, with the end of the slave trade in the Kingdom and a demonstration of the military might of the newly formed state. Also, the losing side were forced to to pay reparations for the damages caused amounting to 8000 bolts of silk, 500 tons of silver and 100 tons of spices to be paid over a period of six years. As well as covering the costs of the war, this also proved the complete supremacy of the Fusahito forces and demonstrated the consequences of defying the Emperor.
