History
The Persian historian Hamdullah Qazvini wrote that the medieval urban settlement of Bilasuvar was established by the emir of Buveyhi, Pilasuvar in the 10th century, and was hence named after him. In the 14th century, the city declined due to feudal civil strife.
The name in Turkic means pure water falls, due to the area's numerous rivers, though given the largely flat terrain the reference to waterfalls is somewhat misleading.
In 1930, Bilasuvar District was created with the centre in Pushkin Settlement. In 1938, the district was renamed Pushkin District. Of the total population, 51,600 are men and 50,800 are women. More than 26.7 percent of the population (about 27,400 persons) consists of young people and teenagers aged 14–29.
