who proclaimed that the western frontier was closed
Frontier Thesis Turner saw the land frontier was ending, since the U.S. Census of 1890 had officially stated that the American frontier had broken up. He sounded an alarming note, speculating as to what this meant for the continued dynamism of American society as the source of U.S. innovation and democratic ideals was disappearing.[citation needed]
Middle East The term "Middle East" may have originated in the 1850s in the British India Office.[6] However, it became more widely known when American naval strategist Alfred Thayer Mahan used the term in 1902[7] to "designate the area between Arabia and India".[8][9] During this time the British and Russian Empires were vying for influence in Central Asia, a rivalry which would become known as The Great Game. Mahan realized not only the strategic importance of the region, but also of its center, the Persian Gulf.[10][11] He labeled the area surrounding the Persian Gulf as the Middle East, and said that after Egypt's Suez Canal, it was the most important passage for Britain to control in order to keep the Russians from advancing towards British India.[12] Mahan first used the term in his article "The Persian Gulf and International Relations", published in September 1902 in the National Review, a British journal.
