While this type of national park had been proposed previously, the United States established the first "public park or pleasuring-ground for the benefit and enjoyment of the people", Yellowstone National Park, in 1872. Although Yellowstone was not officially termed a "national park" in its establishing law, it was always termed such in practice and is widely held to be the first and oldest national park in the world. However, the Tobago Main Ridge Forest Reserve (established in 1776), and the area surrounding Bogd Khan Uul Mountain (1778) are seen as the oldest legally protected areas, predating Yellowstone by nearly a century.
