Rutherford B. Hayes is one of the most forgettable US presidents, but is revered as a national hero in Paraguay for the following reasons: In the late 1800s, Hayes mediated a border dispute between Paraguay and Argentina after Paraguay's devastating loss in the War of the Triple Alliance, and his decision favored Paraguay by granting them ownership of 60% of the disputed territory. This ruling was crucial in allowing Paraguay to recover from the war and ensured its survival as an independent nation. As a result, many cities, landmarks, and institutions in Paraguay are named after Hayes today, and November 12th - the day he signed the ruling - remains a national holiday.
