Rocky Mountain National Park was established in 1915. The 265,000-acre park straddles part of the Continental Divide. About one-third of the park supports an alpine tundra ecosystem. Visitors can hike over 300 miles of trails, and scientists come here to study bighorn sheep.

Coast Guard was created by Congress in 1915. It was derived from the Life Saving and Revenue Cutter Service. The Coast Guard has three goals: maritime safety, maritime security, and maritime stewardship.
RMS Lusitania sank in 1915. It was torpedoed by Germany, and 1,198 people, including 128 Americans, died. The ship was traveling from New York to Liverpool, England. The United States protested the action, but Germany countered that the ship held munitions for England and was fair game. The sinking created anti-German feelings in the United States, and America declared war on Germany on April 4, 1917.
