Russia also bore the brunt of the Mongol invasion of Europe in the 1230’s, during which the Mongols razed many of Russia’s cities and put their populations to the sword.

Keep in mind that the foundation of Russian civilization was formed by the remnants of the Byzantine Empire, after it collapsed in 1453. Russians would fight the Golden Horde later, but they really weren't around in the 1200s.

The Russian state may not yet have formed in the 1200’s, but Russians were definitely around. The Teutonic Knights learned about them during the Battle of Lake Peipus in 1242. The depiction of that battle in Sergei Eisenstein’s movie Alexander Nevskii is one of the greatest battle scenes that I have ever seen.
