Though history is usually written by the victors, the lack of a particularly strong writing tradition from the Mongols ensured that history was largely written by those who they vanquished. Because of this, their portrayal in the West and the Middle East has been extraordinarily (and in many ways unfairly) negative for centuries, at least until recent revisions to the historical record. The Mongols have long been depicted as wild horse-archers galloping out of the dawn to rape, pillage, murder and enslave, but the Mongol army was a highly sophisticated, minutely organized and incredibly adaptive and innovative institution, as witnessed by the fact that it was successful in conquering enemies who employed completely different weaponry and different styles of fighting, from Chinese armored infantry to Middle Eastern camel cavalry and Western knights and men-at-arms.
Geographically the Tatars descend from several parts of Asia, particularly Central Asia, but the Crimean region has been the nexus of several great power rivalries and numerous conflicts. Yet the Crimean Tatars endured through many of these, aligning themselves with a number of larger powers and developing a reputation as fearsome warriors. Today the Tatars are mainly linked with and live in the Volga region of the Russian Federation. Indeed, Tatarstan is a republic in modern Russia. The "Volga Tatars" are perhaps the best known of the peoples known as Tatars and today number about 5 million people.
Before the Mongols rode across the steppes of Asia and Eastern Europe, the Cumans were a major military and cultural force that monarchs from China to Hungary and from Russia to the Byzantine Empire faced, often losing armies and cities in the process. The Cumans were a tribe of Turkic nomads who rode the steppes looking for plunder and riches, but they rarely stayed long after they got what they wanted.
