Dollar Diplomacy was a foreign policy created by President William Howard Taft and Secretary of State Philander C. Knox. It was made to ensure financial stability of a region while protecting Americas financial interest. Instead of committing to military governments he wanted to help governments improve their economies by becoming more legitimate. He also wanted to help improve the United States and to limit the other great powers and Dollar diplomacy helped do that. U.S financial interests helped build railroads, canals, and roads for trade in other countries. Some say Dollar diplomacy was a failure because some say it led to global conflict through competition. http://history.state.gov/milestones/1899-1913/dollar-diplo
