Tartaria

Tartaria: The homeland of the Mongols—whose people were known in Dati's day as Tartars or Tatars—was centered on the steppes of central Asia north and east of the Black Sea and Caspian Sea. In the 13th century the Mongol Empire stretched from Poland and the Crimea to China, but by the 15th century, however, the Empire had splintered into multiple smaller khanates, with unpredictable results for European traders hoping to cross central Asia. The khanate to the northeast of the Black Sea was generally known as the Golden Horde.
