Gediminas, Grand Duke of Lithuania, pursued an expansionist campaign southward, first conquering Volhynia and then directing his forces toward Kiev. Prince Stanislav of Kiev allied with the Principalities of Pereyaslavl and Bryansk to resist Lithuanian encroachment into the region.
The Battle on the Irpin River, reportedly fought in the early 1320s, saw Lithuanian forces defeat the combined armies of Kiev, Pereyaslavl, and Bryansk. However, no contemporary sources confirm the battle; it appears only in late Lithuanian Chronicles, leading historians to debate whether the engagement was real or a later invention.
According to the chronicles, the Lithuanian victory extended their sphere of influence to Kiev. Full Lithuanian control of the city was not achieved until 1362, when Lithuania defeated the Golden Horde at the Battle of Blue Waters. The battle's disputed nature makes its political consequences difficult to assess with confidence.
