Livonian War

▪ Russian history

      (1558–83), prolonged military conflict, during which Russia unsuccessfully fought Poland, Lithuania, and Sweden for control of greater Livonia—the area including Estonia, Livonia, Courland, and the island of Oesel—which was ruled by the Livonian branch of the Teutonic Knights (Order of the Brothers of the Sword (Brothers of the Sword, Order of the)).

      In 1558 Ivan IV of Russia invaded Livonia, hoping to gain access to the Baltic Sea and to take advantage of the weakness of the Livonian Knights; he seized Narva and Dorpat and besieged Reval. The Knights, unable to withstand the Russian attack, dissolved their Order (1561); they placed Livonia proper under Lithuanian protection and gave Courland to Poland, Estonia to Sweden, and Oesel to Denmark.

      Ivan was then obliged to wage war against Sweden and Lithuania to retain his conquests in Livonia. Initially successful, the Russians captured Polotsk, in Lithuanian Belorussia (1563), and occupied Lithuanian territory up to Vilna. In 1566 the Russian zemsky sobor (“assembly of the land”) refused a Lithuanian peace proposal. But as the war progressed, Russia's position deteriorated; during the 1560s Russia experienced severe internal social and economic disruptions while Lithuania became stronger, forming a political union with Poland (1569) and acquiring a new king, Stephen Báthory (1576).

      Báthory launched a series of campaigns against Russia, recapturing Polotsk (1579) and laying siege to Pskov. In 1582 Russia and Lithuania agreed upon a peace settlement (Peace of Yam Zapolsky), whereby Russia returned all the Lithuanian territory it had captured and renounced its claims to Livonia. In 1583 Russia also made peace with Sweden, surrendering several Russian towns along the Gulf of Finland (its only access to the Baltic Sea) and giving up its claims to Estonia.
