Answer: Syria
Notes: Egypt and Syria formed the United Arab Republic (UAR) in 1958. The UAR was a sovereign state that was intended to be the first step toward a pan-Arab union. The union was short-lived, ending in 1961 when Syria seceded. Egypt continued to be known as the United Arab Republic until 1971.  The UAR was formed as a single political unit with Gamal Abd al-Nasser as its president. Nasser gave each province two vice-presidents. The provisional constitution of 1958 was adopted. The United States recognized the UAR on February 25, 1958.
