Persia was a state in Western Asia with its capital in Tehran. In 1921 Reza Khan, an officer of the Persian Cossack Brigade, carried out a coup; in 1925 the Majlis deposed the Qajar dynasty, and Reza Khan soon became shah as Reza Shah Pahlavi. He strengthened central authority, built a regular army and in 1927 began construction of the Trans-Iranian Railway. In 1935 the government asked foreign countries to call the country Iran.
