Vyatka
Vyatka was a commonwealth of Russian settlers in the Vyatka River basin, with its chief town at Khlynov. Its communities governed their affairs through a popular assembly and only intermittently acknowledged outside overlords.
In 1374 a band of Vyatka river raiders attacked Sarai, capital of the Golden Horde; around 1383 Nizhny Novgorod made Vyatka a dependency. Moscow's Vasily I granted it to his brother Yury in 1402, but its raiders sacked Sarai again in 1471. In 1489 Ivan III subdued Vyatka, deported its notables and absorbed it into Muscovy.
