The various Mongol Khanates may get a reprieve to unite against Moscow and Russia would not exist.
It should be remembered that Ivan the Terrible is a mistranslation of Ivan the Awesome. To Russians of that era being terrible is terrific!
Yes well, regardless Russia might not exist without Ivan.Its worth noting that the descendents of the Golden Horde in western Russia had long lost their Mongolian character by the Sixteenth Century. By this era, they were often referred to as "Tatars" by their contemporaries, and were more closer in culture to the Ottoman Turks than they were to their Mongol forebears.
