Uezd

Uezds were ruled by the appointees (namestniki) of a knyaz and, starting from the 17th century, by voyevodas.

In 1708, an administrative reform was carried out by Peter the Great, dividing Russia into governorates.

The subdivision into uyezds was abolished at that time but was reinstated in 1727, as a result of Catherine I's administrative reform.

In UkSSR, uezds were reformed into forty okruhas which were the primary-level of administrative division from 1925 to 1930.

The uezds of Bessarabia Governorate were called Ținut or Județ in Romanian, which would translate as "county".
