U.S. diplomatic interaction with Turkey dates back to the days when Turkey was known as the Ottoman Empire. After they established diplomatic relations in 1831, the states maintained a diplomatic relationship until U.S. entry into World War I on April 20, 1917. After World War I, the Ottoman Empire dissolved, and in its place arose the modern state of Turkey, with which the United States reestablished relations in 1927.
