Before 1917, America did not get involved in the alliance system of Europe due to the following reasons:
1. Neutrality: The United States maintained a policy of neutrality, intending to stay out of the conflicts and rivalries between European powers. This approach was influenced by President George Washington's Farewell Address, where he advised against entangling alliances.
2. Focus on domestic issues: The U.S. was primarily focused on its own internal development and expansion during this period. The country was involved in westward expansion, industrialization, and economic growth. Therefore, there was little desire or perceived need to involve itself in European affairs.
3. Monroe Doctrine: The Monroe Doctrine, declared in 1823, stated that the United States would oppose any further colonization efforts by European powers in the Americas. This doctrine aimed to protect American interests and prevent European interference in the region. As a result, the U.S. focused on maintaining its influence in the Western Hemisphere rather than engaging in European alliances.
4. Geographic distance: The geographical separation between Europe and the United States played a role in America's non-involvement. The Atlantic Ocean acted as a physical barrier, making it logistically challenging and time-consuming to intervene in European conflicts. This distance contributed to a sense of isolationism and reinforced the idea of staying out of European affairs.
It's important to note that while the United States initially maintained a policy of non-involvement, this stance shifted with its entry into World War I in 1917. The war and subsequent events led to a reevaluation of American foreign policy and a more active role in international affairs.
