United States Marines occupied Nicaragua from 1912 to 1933, except for a nine-month period beginning in 1925. In 1914, the Bryan–Chamorro Treaty was signed, giving the U.S. control over a proposed canal through Nicaragua, as well as leases for potential canal defenses. Following the evacuation of U.S. Marines, another violent conflict between Liberals and Conservatives took place in 1926, which resulted in the return of U.S. Marines.
