Bilasuvar () is a city in and the capital of the Bilasuvar District of Azerbaijan. The area's considerable agricultural potential depends on irrigation. It is situated near one of the country's four border crossings with Iran.
It has been said that the city's name was called "Pileh-Swar", which meant âÂÂElephant-riding Personâ in Persian language, a reference to an early emir. In Azerbaijani the name means âÂÂPure WaterfallsâÂÂ.
The city is located in the Central Aran region. BilÃÂsuvar was divided into two parts in 1828 with the Turkmanchay Treaty between Qajar Iran and the Russian Empire, which concluded the Russo-Persian War (1826âÂÂ1828). The similarly-named Iranian city of Bileh Savar is located right across the border.
