Tehran

In classical antiquity, part of the territory of present-day Tehran was occupied by Rhages, a prominent Median city that was destroyed in the medieval Arab, Turkic, and Mongol invasions. Modern Ray was absorbed into the metropolitan area of Greater Tehran. Tehran was first chosen as the capital of Iran in 1786 by Agha Mohammad Khan of the Qajar dynasty, because of its proximity to Iran's territories in the Caucasus—which were contested in the Russo-Iranian Wars—and to avoid the vying factions of prior ruling Iranian dynasties; the capital of Iran had been moved several times throughout its long history, with Tehran becoming the 32nd. Under Naser al-Din Shah (r. 1848–1896), Tehran witnessed Iran's first institute of higher learning, bank, railway line, and museum. Large-scale construction works began in the 1920s, and Tehran became a destination for mass migrations from all over Iran especially in the 20th century. Tehran was at the center of the Iranian Revolution, and experienced major bombing damage during the Iran–Iraq War, the Twelve-Day War, and the 2026 Iran war.
