 His books have been translated into more than 170 languages.Dostoevsky's parents were part of a multi-ethnic and multi-denominational noble family, its branches including Russian Orthodox Christians, Lithuanian nobility, Polish Roman Catholics and Ukrainian Eastern Catholics.The family traced its roots back to a Tatar, Aslan Chelebi-Murza, who in 1389 defected from the Golden Horde and joined the forces of Dmitry Donskoy, the first prince of Muscovy to openly challenge the Mongol authority in the region, and whose descendant, Danilo Irtishch, was ennobled and given lands in the Pinsk region (for centuries part of the Grand Duchy of Lithuania, now in modern-day Belarus) in 1509 for his services under a local prince, his progeny then taking the name "Dostoevsky" based on a village there called Dostoïevo.
