Ontsifor Lukinich

Ontsifor Lukinich (died 1367) was a boyar of the Novgorod Republic from the Mishinichi clan. He used popular movements against the boyars to advance, and is first recorded in 1342 leading a city uprising for which he was exiled but soon returned.

In 1348 he led the Novgorod army that defeated King Magnus Eriksson of Sweden after the Swedes seized Oreshek fortress. He served as posadnik from 1350 to 1354 and in 1354 carried through the posadnik reform, creating six lifetime posadniki from the city's different ends, with a presiding one chosen each year; he himself declined that office.
