What were the major goals and principles of American foreign policy from 1865 1914?

From 1865 to 1914, major goals of American foreign policy included expanding territorial influence, promoting economic interests, and asserting itself as a global power. Key principles during this period were manifest destiny, which justified westward expansion, and the Open Door Policy, aimed at ensuring equal trading rights in China. Additionally, the U.S. sought to prevent European intervention in the Americas through the Monroe Doctrine, emphasizing a stance of non-interference while also engaging in imperialist ventures, such as the Spanish-American War. Overall, the era marked a transition from isolationism to a more interventionist approach in global affairs.
