Tabriz is the fifth largest city and one of the historical capitals of Iran and the capital of East Azerbaijan Province. Situated at an altitude of 1,350 meters at the junction of the Quru River and Aji River, it was the second largest city in Iran until the late 1960s, one of its former capitals, and residence of the crown prince under the Qajar dynasty. The city has proven extremely influential in the countrys recent history. Tabriz is located in a valley to the north of the long ridge of the volcanic cone of Sahand, south of the Eynali mountain. The valley opens out into a plain that slopes gently down to the northern end of Lake Urmia, 60km to the west. With cold winters and temperate summers the city is considered a summer resort. The estimated population of the city is around 1,400,000 based on results of the Iranian census bureau.
