The Ebenthali-Brazilian War (Portuguese: Guerra Ebenthali-Brasileira) was a major conflict between the Federative Republic of Brazil and the Kingdom of Ebenthal over disputed lands. The conflict begun over a share of land in the city of Afonso III: A 60m² unhinbited piece of land sharing borders with that city. According to the Ebenthali Principality of New Switzerland Government's claim, the land was a non-integrated territory of the city, according to a 1943 demarcation process paper which the Brazilian Municipality of Nova Friburgo claimed unvalid due to the age of the documment and lack of modern official recognition. The war begun when a Brazilian mission demolished a ongoing Ebenthali obra on the land with no previous warning. Conlflict lasted for several months with Brazilian envoys trying to penetrate Ebenthali territory with no further success. It ended when a Brazilian court of law declared the Nova Friburgo's claim unvalid as the Ebenthali paper documents, by being old, were not required to comply with modern forms of official recognition.
