The Historical Reason For Building Salam Hall In Golestan Palace

  Tehran's arg ("citadel") was built during the reign of Tahmasp I (r. 1524–1576) of the Safavid dynasty (1502–1736), and was later renovated by Karim Khan of the Zand dynasty (r. 1750–1779). Agha Mohammad Khan of the Qajar dynasty (1742–1797) chose Tehran as his capital. The arg became the seat of the Qajars (1794–1925). The court and palace of Golestan became the official residence of the Qajar dynasty. The palace was rebuilt to its current form in 1865 by Haji Ab ol Hasan Mimar Navai.
