(properly Tatary). Is the name under which, in the Middle Ages, was comprised the whole central belt of Central Asia and Eastern Europe, from the Sea of Japan to the Dnieper, including Mantchuria, Mongolia, Eastern Turkestan, Independent Turkestan, the Kalmuck and the Kirghis steppes, and the old khanates of Kasan, Astrakhan, and the Crimea, and even the Cossack countries; and hence arose a distinction of Tartary into European and Asiatic. But latterly the name Tartary had a much more limited signification, including only that tract bounded on the north by Siberia, and on the south by China and Thibet, along with Independent Turkestan; and at the present day, many writers apply it as a synonym for Turkestan. The Tartars (or, more properly, Tatars) was originally a name of the Mongolic races, but came to be extended to all the tribes brought under Mongolic sway by Genghis Khan and his successors, including Tungusic and Turkic races. The term is therefore not to be considered as ethnological, though all, or almost all, the peoples included under it, in its widest sense, belong to the Turanian family, but is rather to be understood in the same sense as the term “Franks” used by the Mohammedans. During the decline of the Roman empire, these tribes began to seek more fertile regions; and the first who reached the frontier of Italy were the Huns, the ancestors of the modern Mongols. The first acknowledged sovereign of this vast country was the famous Genghis Khan. His empire by the conquest of China, Persia, and all Central Asia (1206-27), became one of the most formidable ever established; but it was split into parts in a few reigns. Timur, or Tamerlane, again conquered Persia, broke the power of the Turks in Asia Minor (1370-1400), and founded the Mogul dynasty in India, which began with Baber in 1525, and formed the most splendid court in Asia, till the close of the 18th century. The Calmucks, a branch of the Tartars, expelled from China, settled on the banks of the Volga in 1672, but returned in 1771, and thousands perished on the journey.
