Muscovite–Lithuanian Wars: The Grand Duchy of Lithuania achieved one of the greatest Lithuanian victories against the Tatars at the Battle of Kletsk.

The Muscovite–Lithuanian Wars were a series of wars between the Grand Duchy of Lithuania and the Grand Duchy of Moscow, which was later unified with other Russian principalities to eventually become the Tsardom of Russia. After several defeats at the hands of Ivan III and Vasily III, the Lithuanians were increasingly reliant on Polish aid, which eventually became an important factor in the creation of the Polish–Lithuanian Commonwealth. Before the first series of wars in the 15th century, the Grand Duchy of Lithuania controlled vast stretches of Eastern European land, from Kiev to Mozhaysk, following the collapse of Kievan Rus' after the Mongol invasions. Over the course of the wars, particularly in the 16th century, the Muscovites expanded their domain westwards, taking control of many principalities.

The Grand Duchy of Lithuania was a sovereign state in northeastern Europe that existed from the 13th century, succeeding the Kingdom of Lithuania, to the late 18th century, when the territory was suppressed during the 1795 partitions of Poland–Lithuania. The state was founded by Lithuanians, who were at the time a polytheistic nation of several united Baltic tribes from Aukštaitija. By 1440 the grand duchy had become the largest European state, controlling an area from the Baltic Sea in the north to the Black Sea in the south.

Tatars are a group of Turkic speaking peoples across Eastern Europe and Asia who bear the name "Tatar".

The Battle of Kletsk was fought on 5 August 1506 near Kletsk, between the Grand Ducal Lithuanian Army, led by Court Marshal of Lithuania Michael Glinski, and the army of the Crimean Khanate, led by Fetih I Giray and Burnaş I Giray, sons of the Khan of Crimea, Meñli I Giray. The battle was one of the first and greatest Lithuanian victories over the Tatars.
