Book excerpt: The outermost khanate of the Mongol Empire was the Golden Horde, which conquered the Rus’ in northwestern Russia in the thirteenth century and continued to rule there in some capacity until the Russian Empire annexed Crimea, the khanate’s last holdout, in 1783. Despite vast cultural and geographic differences between Rus’ and the Mongols’ traditional homeland on the steppes of Central Asia, the Golden Horde flourished, with Moscow becoming the dominant principality. This fascinating and little-known history is related in thrilling, panoramic narrative detail and includes profiles of Rus’ leaders such as Alexander Nevsky and Daniel of Moscow.
