The nation’s earlier isolationism originated from the deep scars left by the Civil War and its need to recover both economically and mentally from that event. But as the industrial revolution changed the way the country worked and the American West reached its farthest point, American attitudes toward foreign expansion shifted. Businesses sought new markets to export their factory-built goods, oil, and tobacco products, as well as generous trade agreements to secure access to raw materials. Early social reformers saw opportunities to spread Christian gospel and the benefits of American life to those in less developed nations. With the rhetoric of Fredrick J. Turner and the strategies of Alfred Mahan underpinning the desire for expansion abroad, the country moved quickly to ready itself for the creation of an American empire.
