The national park first came to be in 1872 by a bill created by President Ulysses S. Grant. The Organic Act of 1916 created the national parks service to conserve the scenery and the natural and historical objects and wildlife therein, and to provide for the enjoyment of the dame in such manner and by such mean as will leave them unimpaired for the enjoyment of future generations. Twenty-nine states currently have state parks, as well as American Samoa and the Virgin Islands. As of now, California has the most state parks with nine.
