After the weakening of Turkish-Armenian relations and intensive American missionary activities, Armenians began to leave their homelands for educational, economic and political reasons. Emigration to the United States intensified in particular in response to the 1915 Techir (Relocation and Resettlement) Law. After achieving political rights in the United States, Armenian immigrants formed groups that began trying to influence U.S. government policy, working to win recognition of the alleged Armenian Genocide, financial assistance for Armenia, and other policies favorable to Armenia. The process that began resolution the alleged Armenia Genocide was removed from the historical dimension and moved to the political dimension and an international policy instrument was created. In the United States, the Armenian Diaspora strives to influence government policy systematically through diaspora organizations that carefully follow the international scene and advocate for United States foreign policies in favor of Armenia. In this study, the ultimate aims of the Armenia Diaspora over American politics and policy-making, and the activities of the Armenian Lobby will be examined.
