Shiraz is the fifth-most-populous city of Iran and the capital of Fars province, which is historically known by the exonym Persia proper. As of the 2016 national census, the population of the city was 1,565,572 people, and its built-up area with Sadra was home to almost 1,800,000 inhabitants. A census in 2021 showed an increase in the city's population to 1,995,500 people. Shiraz is located in southwestern Iran on the rudkhaneye khoshk (lit. 'dry river') seasonal river. The city has a moderate climate and has been a regional trade center for over a thousand years.
The earliest reference to the city, as Tiraziš, is on Elamite clay tablets dated to 2000 BCE. The modern city was founded by the Sasanian dynasty and restored by the Umayyad Caliphate in 693 CE and grew prominent under the successive Iranian Saffarid and Buyid dynasties in the 9th and 10th–11th centuries, respectively. In the 13th century, Shiraz became a leading center of the arts and letters, due to the encouragement of its ruler and the presence of many Persian scholars and artists. Two famous poets of Iran, Hafez and Saadi, are from Shiraz, whose tombs are located on the north side of the current city boundaries.
