Early history

The Svislach River valley was the settlement boundary between two early East Slavic tribes – the Krivichs and Dregovichs. By 980, the area was incorporated into the early medieval Principality of Polotsk, one of the earliest East Slavic principalities of Kievan Rus'. Minsk was first mentioned in the name form Měneskъ (Мѣнескъ) in the Primary Chronicle for the year 1067 in association with the Battle on the River Nemiga. 1067 is now widely accepted as the founding year of Minsk. City authorities consider the date of 3 March 1067 to be the exact founding date of the city, though the town (by then fortified by wooden walls) had certainly existed for some time by then. The origin of the name is unknown but there are several theories.

In the early 12th century, the Principality of Polotsk disintegrated into smaller fiefs. The Principality of Minsk was established by one of the Polotsk dynasty princes. In 1129, the Principality of Minsk was annexed by Kiev, the dominant principality of Kievan Rus'; however in 1146 the Polotsk dynasty regained control of the principality. By 1150, Minsk rivalled Polotsk as the major city in the former Principality of Polotsk. The princes of Minsk and Polotsk were engaged in years of struggle trying to unite all lands previously under the rule of Polotsk.
