Additionally, the voyage of the Great White Fleet demonstrated both at home and on the world stage that the U.S. had become a major sea power in the years after its triumph in the Spanish–American War, with possessions that included Guam, the Philippines, and Puerto Rico. This was not the first demonstration of naval power however; during the Algeciras Conference in 1906, which was convened to settle a diplomatic crisis between France and Germany over the fate of Morocco, Roosevelt had ordered eight battleships to maintain a presence in the Mediterranean Sea. Since Japan had arisen as a major sea power with the 1905 annihilation of the Russian fleet at Tsushima, the deployment of the Great White Fleet was therefore intended, at least in part, to send a message to Tokyo that the American fleet could be deployed anywhere, even from its Atlantic ports, and would be able to defend American interests in the Philippines and the Pacific.
