Hayes' intervention in an international border dispute between Paraguay and Argentina, arbitrated in favor of Paraguay. The area that becamePresidente Hayes Department with its capital city ofVilla Hayes was named for the U.S. president who awarded an area that comprises 60 percent of modern Paraguay to the country while arbitrating a boundary dispute between Paraguay and Argentina after theParaguayan War, which Paraguay lost, and in which hundreds of thousands died, including more than half of Paraguay's population. The dispute over the remote "Chaco Boreal", theGran Chaco region andChaco (Paraguay) specifically was settled. The area is sparsely populated and includes many indigenous people. The compromise was reached after 8 years of negotiations on November 12, 1878.[2]
