Growing Muscovite power clashed with Lithuanian interests after Lithuania absorbed Kiev following the Battle of Blue Waters in 1362. Algirdas repeatedly supported Tver, Moscow's chief rival, and attempted to install his brother-in-law Mikhail II of Tver on the Vladimir throne, prompting three Lithuanian military campaigns against Moscow between 1368 and 1372.
In the summer of 1372, a Lithuanian army advanced toward Moscow but was halted near the fort of Lyubutsk on the Oka River, northeast of Tula. Lithuanian vanguard forces were defeated and retreated. With Algirdas holding a defensive position in the hills and Dmitri Donskoi's army facing him, both sides entered a standoff that concluded in a negotiated peace treaty.
Algirdas renounced his backing of Mikhail II of Tver, ending Lithuania's active support for Moscow's rivals. The failed campaigns strengthened Moscow's prestige across Rus' and signaled that Lithuanian expansion eastward into Slavic territories had reached its practical limit. Peace held for about seven years until 1379, when Algirdas's son Andrei of Polotsk realigned with Moscow after his father's death in 1377.
Political Outcome
Peace treaty ended the Lithuanian–Muscovite War; Lithuania abandoned support for Tver's claims and recognized Moscow's growing sphere of influence.
Lithuania actively contested Muscovite dominance in Rus' by supporting Tver and campaigning against Moscow.
Moscow's prestige consolidated; Lithuanian eastward expansion into Slavic lands effectively ceased.
