The Mongol invasion, although destructive for probably all civilizations of the time, had definitively a positive effect to the survival of eastern romance culture. In the dark ages the amount of migrating population was so great that for quite some time they outnumbered the descendants of the former Roman Empire around Carpathians and Balkans. The dominance of the vulgar-Latin speaking population suffered serious setbacks and were being confined to smaller and smaller less accessible areas like mountainous regions. The west-most areas of the Mongol raids were around Carpathian Mountains up to Pannonian Basin and were they went through, they basically cleaned the densely-populated lowland of the most of its inhabitants. Its a known fact that the Mongol incursions were disastrous for Hungarians, Poles, Russians, and other populations that were in the region at the time, but on the other hand they were vital for romance population. Of course, the romance population suffered from those raids too, along with other cohabitant populations, but after that, that mountain-descending romance population become dominant again. Have not Mongols come, the fate of the eastern romance population around Carpathians would have been the same as the one of the former eastern romance populations south of Danube - for a while they probably would have managed to manifest some cultural and even political power (like the Vlach-Bulgar Empire of Asănești), but in the end they would have been assimilated completely.
