The Mongol invasions of Lithuania was an event where the Mongol armies invaded the territories of the Kingdom of Lithuania and later, the Grand Duchy of Lithuania, on several occasions in late 13th and early 14th century. The event is not very well documented. In due course, however, the Lithuanians were able to take control of a number of former Mongol territories, expand their influence in Eastern Europe, and contribute to the liberation of neighbouring peoples.[1]
