[1] Previously known as Saird, in pre-Islamic times Siirt was a diocese of the Eastern Orthodox Church (Sirte, Σίρτη in Byzantine Greek).

The Chronicle of Seert was preserved in the city; it describes the ecclesiastical history of the Persian realm through to the middle of the seventh century.

[9] According to the 1927 census, the population in the whole district was almost exclusively Muslim, with the exception of two Catholics, one Protestant, four Armenians, 17 other Christians, and 38 "other religion".

[19] On January 29 2025, another elected mayor from the pro-Kurdish DEM party was removed from office due to "convictions on terrorism-related offenses", according to the Interior Ministry, and was replaced by a state official.

Although Siirt remains one of the poorer cities in Turkey, some neighbourhoods have fine and modern housing including new shops, banks and hotels.

[21] Siirt has a hot-summer Mediterranean climate (Köppen: Csa, Trewartha: Cs) with very hot, dry summers and chilly, wet winters.
