During the 13th and 14th centuries, the Mongols  launched two long, massive invasions of the territory of modern Chechnya (then the Georgian-allied Vainakh kingdom of Dzurdzuketia). They caused massive destruction and human death for the Dzurdzuks, but also greatly shaped the people they became afterward. The ancestors of the Chechens and Ingush bear the distinction of being one of the few peoples to successfully resist the Mongols, not once, but twice, but this came at great cost to them, as their state was utterly destroyed. These invasions are among the most significant occurrences in Chechen history, and have had long-ranging effects on Chechnya and its people.
