Truce of Vilna
peace treaty

The Truce of Vilna, Treaty of Wilno or Truce or Treaty of Niemieża was a treaty signed at Niemieża (modern Nemėžis) near Vilnius (also known as Vilna or Wilno) on 3 November 1656 between the Tsardom of Russia and Polish–Lithuanian Commonwealth, introducing a truce during the Russo-Polish War (1654–67) and an anti-Swedish alliance in the contemporaneous Second Northern War. In return for ceasing hostilities and fighting Sweden alongside Poland–Lithuania, the treaty promised tsar Alexis of Russia to succeed the Polish–Lithuanian throne as soon as John II Casimir Vasa would die. Thus began the Russo-Swedish War (1656–1658), which Russia would lose.
The Cossack Hetmanate under Bohdan Khmelnytsky was excluded from the negotiations, and the Truce did nothing to address the Muscovite occupation of Lithuania and the status of Ukraine. The Ukrainian Cossacks were enraged by this Russian betrayal of the 1654 Pereiaslav Agreement that promised Muscovite military support for the Cossacks against the Commonwealth. Without their knowledge or consent, the Russian tsar had suddenly made a separate peace deal with the Commonwealth, and violated his duty of military protection of the Cossacks. Khmelnytsky therefore ignored the Truce of Vilna, and subsequently supported the Transylvanian invasion of Poland on the Swedish side.
Developments
After a series of successes for the Russian forces, with an even more successful Swedish invasion of the Polish–Lithuanian Commonwealth, the Russian tsar decided that total defeat of the Commonwealth and a Swedish victory leading to a major strengthening of Sweden (a threat to Russia) would not be in the best interests of Russia.
The negotiations began in Autumn of 1655, between Field Hetman of Lithuania Wincenty Korwin Gosiewski and Russian commander Afanasy Ordin-Nashchokin, and led to a quick ceasefire along the Polish-Russian front, allowing the Commonwealth to concentrate on the Swedish incursion. In the light of its successes, the Commonwealth's stance in the negotiations intensified, and it has rejected Russian territorial demands; however, both Poland and Russia agreed to continue engaging Sweden.

Why this record matters
“Truce of Vilna” is worth following because a concise public description often conceals a longer documentary argument. Here, Truce, Vilna and peace provides the most credible route into that argument.
The record creator and administrative purpose are central evidence, because official documentation reflects both action and institutional priorities. The source revision retrieved here is dated Sep 13, 2026. The linked authority identifier is Q1502680. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1656, 1654, 1658 and 1655.
Later summaries often reconcile disputed chronology or motive more neatly than the contemporary record permits. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
