Balasagun (Balassagun, Balasaghun, Karabalsagun; Chinese: 八剌沙衮; pinyin: bālàshāgǔn, Persian: بلاساغون) was an ancient Soghdian city in modern-day Kyrgyzstan, located in the Chui River valley between Bishkek and Lake Issyk-Kul.
Balasagun was founded by Soghdians, a people of Iranian origin and the Soghdian language was still in use in this town till the 11th century.[1]
It was the capital of the Kara-Khitan Khanate from the 10th Century until the Mongols captured it in 1218. The Mongols called it Gobalik (”pretty city”). It should not be confused with the city of Karabalghasun in Mongolia which was the capital of the Uyghur Khaganate.
