Year 1313
You invaded and conqered most of Kievan principiality, part of Smolensk principiality, all of Polotsk, took part of Novgorod principiality, while we were suffering under the mongol yoke. You are the sole reason why Ukraine and Belarus even exist. That was a war on two fronts, we had to fight both you (and lithuania) and the mongols, at which we failed and could only retake all our land in 300 years.
>bear in mind that we also fought against the MongolsYou did fight the mongols, but only when they attacked you.You completely ignored the issue and didn't come to our rescue, quite the opposite, you were massing an army to invade us while we were getting sacked by mongols, and after repelling the mongols from your lands you continued to expand and took a great chunk of our land, leaving the eatern part of our country no chance to defeat the chinks and forcing the western parts to live as your serfs. We had to suffer through 300 years of oppression entirely because of you.
