Source-derived summary

Demian Ihnatovych (Ruthenian: Демко Ігнатович / Демянъ Игнатович(ъ), Ukrainian: Дем'ян Ігнатович; 1621, Korop – 1703), popularly known under the nickname Mnohohrishny (Ukrainian: Многогрішний, Polish: Damian Mnohohriszny, literally "of many sins") was the Hetman of Left-bank Ukraine from 1669 to 1672, during the period known as the Ruin. In 1689 he participated in signing of the Treaty of Nerchinsk and became de facto voivode of Buriatia (1691–1694).

Biography

Demian Ihnatovych (Mnohohrishny) was born in Korop, Chernihiv Voivodeship (today part of Chernihiv region).

He took part in the National Liberation War under the leadership of Bohdan Khmelnytsky. From 1665 to 1668 he held the government of Chernihiv Regiment.

In 1668 Ihnatovych, as an opponent of the Treaty of Andrusovo, according to which Ukraine was divided along the Dnieper into the Right Bank under the control of the Commonwealth and the Left Bank controlled by Muscovy, took part in the anti-Moscow uprising. He was one of the first colonels to side with the Right Bank Hetman Petro Doroshenko, proposing him to unite all of Ukraine under his mace.

In 1668 he was appointed acting hetman of Left-bank Ukraine. Lack of military assistance from Petro Doroshenko, strong Moscow garrisons in the Left Bank cities and pressure from the pro-Moscow part of the officers and the Orthodox clergy prompted Demian Ihnatovych to negotiate with the tsarist government. On December 17, 1668, by the decision of the Novhorod-Siversky Cossack Council, Ihnatovych headed the government in the Left Bank and on behalf of all the officers continued negotiations with the tsar.

Editorial summary

The public source identifies “Demian Mnohohrishny” as hetman of Ukrainian Cossacks. This brief keeps that definition visible, then builds a research path around Demian, Mnohohrishny and Hetman.

Editorial reviewA dependable orientation record for establishing vocabulary, names and a first evidence trail. The current lead gives the account dated anchors—1621, 1703, 1669, 1672—that can be checked directly. The authority record carries competing date values—1621, 1631-01-01—which should remain separate until their references and qualifiers are resolved. Its value is orientation rather than verdict, with Demian, Mnohohrishny and Hetman providing the first useful test.

Critical limits
