In the late nineteenth and early twentieth centuries political and military leaders reformed the US federal government to establish a stronger central government than had ever previously existed for the purpose of enabling the nation to pursue an imperial policy in the Pacific and in the Caribbean and economic militarism to support the development of the new industrial economy. This reform was the result of a conflict between Neo-Hamiltonian Republicans and Jeffersonian-Jacksonian Democrats over the proper administration of the state and direction of its foreign policy. The conflict pitted proponents of professionalism, based on business management principles, against those favoring more local control in the hands of laymen and political appointees. The outcome of this struggle, including a more professional federal civil service and a strengthened presidency and executive branch, made a more expansionist foreign policy possible.
