Government could guarantee access to these new international markets. What concerned Mahan most was ensuring that the U.S. economy would soon be unable to absorb the massive amounts of industrial and commercial goods being produced domestically, and he argued that the United States should seek new markets abroad. Mahan was one of the foremost proponents of the "vigorous foreign policy" referred to by Turner. While Turner did not explicitly argue for a shift towards commercial expansion overseas, he did note that calls for a "vigorous foreign policy" were signs that Americans were increasingly looking outside the continental United States in order to satiate their desire for new economic opportunities and markets. Mahan's books complemented the work of one of his contemporaries, Professor Frederick Jackson Turner, who is best known for his seminal essay of 1893, "The Significance of the Frontier in American History." An American history professor at the University of Wisconsin, Turner postulated that westward migration across the North American continent and the country's population growth had finally led to the "closing" of the American frontier, with profound social and economic consequences. The publication of Mahan's books preceded much of the disorder associated with the 1890s, but his work resonated with many leading intellectuals and politicians concerned by the political and economic challenges of the period and the declining lack of economic opportunity on the American continent. The 1890s were marked by social and economic unrest throughout the United States, which culminated in the onset of an economic depression between 18. foreign policy, particularly in the quest to expand U.S.

Mahan and some leading American politicians believed that these lessons could be applied to U.S. Mahan argued that British control of the seas, combined with a corresponding decline in the naval strength of its major European rivals, paved the way for Great Britain's emergence as the world's dominant military, political, and economic power. Two years later, he completed a supplementary volume, The Influence of Sea Power upon the French Revolution and Empire, 1793-1812. In 1890, Captain Alfred Thayer Mahan, a lecturer in naval history and the president of the United States Naval War College, published The Influence of Sea Power upon History, 1660-1783, a revolutionary analysis of the importance of naval power as a factor in the rise of the British Empire.
