Poliudie

The poliudie (Russian: полюдье) was the practice of gathering tribute by the rulers of Kievan Rus' from vassal East Slavic and Finnic tribes.

[2] In winter, the ruler of Kiev went out on rounds, visiting Dregovichs, Krivichs, Drevlians, Severians, and other subordinated tribes.

The chronicle reports that Olga's husband, Igor, was killed by the Drevlians angered at his attempt to collect more tribute than it had been agreed.

After his death, Olga appointed her own officials to gather and deliver tribute, at least in some of the areas of her domain, preferring not to rely on local chiefs and the system of poliudie.

[5] Valentin Yanin suggests that Olga's reform was the first germ of the law of the Rus', later codified as the Russkaya Pravda.
