"New Sarai" or "Sarai Berke" (called "Sarai-al-Jadid" on coins) is believed to have been either at what is now Kolobovka (formerly Tsarev), an archeological site also on the Akhtuba channel 55 km east-southeast of Volzhsky, and about 180 km northwest of Old Sarai; or possibly on the site of Saqsin (which may itself have stood on the site of the Khazar capital, Atil). The bishops of Krutitsy resided in Tsarev from 1261 to 1454. It had probably succeeded Sarai Batu as the capital of the Golden Horde by the mid-14th century.
