In the context of Advanced Placement United States History (APUSH), the concept refers to the principle that a nation or group of people with similar political aspirations should be free to determine its own political status and form of government without external influence. This often manifested as movements for independence from colonial rule or for greater autonomy within existing political structures. For example, after World War I, the idea played a significant role in the redrawing of national boundaries in Europe, as various ethnic groups sought to establish their own sovereign states.
The significance of this principle within the APUSH curriculum lies in its pervasive influence on American foreign policy, particularly during the 20th century. It informed President Woodrow Wilson’s Fourteen Points and underpinned the rationale for U.S. involvement in both World Wars. Furthermore, the application, or perceived lack thereof, of this ideal fueled anti-colonial movements globally and influenced American relations with emerging nations during the Cold War. Studying this concept provides insight into the complexities of international relations, the tension between national interests and moral principles, and the enduring legacy of colonialism.
