Roman the Great
With time the city of Belz with its surrounded territories was passed to Vsevolod Mstislavich who in turn passed it to his son Alexander. In the early 13th century, Alexander, a nephew of Roman the Great, was deposed in 1234 from Belz by Daniel of Galicia who incorporated Belz into the Duchy of Galicia–Volhynia (later the Kingdom of Rus) which would control Belz till 1340. Soon afterwards, in 1240 and 1241, it was ravaged by the Mongols, as were most other Rus principalities; the town was burned, the local castle destroyed and locals had to recognize the Mongol suzerainty. The Mongol influence waned in the following decades, because of the decline of the Mongol Empire and Pax Mongolica.
