Batu Khan

Son of Jochi and grandson of Genghis Khan, the man who turned the Jochid appanage into the Golden Horde. He commanded the great western invasion that crushed the Rus principalities, sacked Kiev in 1240, and overran Hungary and Poland the following year. His khanate would dominate Russia for the next two and a half centuries — the period the Russians remember as the Tatar Yoke.
