モンゴルのルーシ侵攻
The most prosperity the city achieved was under Rurik Rostislavich, the ruler of Kievan Rus, who made the city his capital. In the 13th century after the Mongol invasion of Rus' Bilhorod degraded and after destruction of Kyiv in 1240 Bilhorod ceased to exist. There is still the small village Bilohorodka near the ruins of the city that keeps its name.
