Viacheslava of Novgorod
Polish queen consort

Viacheslava of Novgorod (Russian: Вячеслава новгородская, Polish: Wierzchosława Nowogrodzka; c. 1125 – 15 March by 1162?), was a Kievan Rus' princess member of the Monomakhovichi and by marriage Duchess of Masovia and Kuyavia and High Duchess of Poland since 1146.
She was the daughter of St. Vsevolod, Prince of Novgorod and Pskov by his wife, a daughter of Svyatoslav Davidovich, Prince of Chernigov.
Life
Nothing is known about Viacheslava's first years; she was one of three children and their only daughter. She had two brothers, Ivan and Vladimir (who was confused in several sources as husband of Princess Richeza of Poland). Both died unmarried and apparently childless.
Around 1137 she was married to Bolesław, son of the Polish Duke Bolesław III Wrymouth. The wedding was probably orchestrated by Bolesław's mother Salomea of Berg, who wanted to secure a Russian alliance against her stepson, the later Władysław II the Exile. On 11 February 1138 Prince Vsevolod died and on 28 October of that year Duke Bolesław III also died, leaving in his will his domains divided between his sons.
This brief starts where responsible research should: with the source description of “Viacheslava of Novgorod” as polish queen consort. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the people & ideas register because the source frames it as polish queen consort. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Chronology provides the most reliable spine for this subject; interpretation should follow only after identities and dates are secure. The source revision retrieved here is dated Jan 3, 2025. The linked authority identifier is Q2465089. VIAF identifies the subject as 316388788. 2 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1125, 1162, 1146 and 1137.
Later biographies can compress uncertainty and repeat inherited reputations, so apparently settled claims may still require comparison. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
