following the second partition of poland, on the newly annexed territory was formed oversized izyaslav vice-royalty (namestnichestvo) which included former polish territories in volhynia, podolia, and kiev land and centered in izyaslav. however couple of years later the russian empire annexed more territories of the polish kingdom during the third partition of poland contributing to the complete disappearance of the polish statehood. the izyaslav vice-royalty was reformed and the territory of today's zhytomyr oblast predominantly ended up in the russian volhynian governorate and the city of zviahel which was renamed as novohrad-volynskyi (novograd-volynskiy) became its administrative center. later the administrative center was transferred to the bigger city of zhytomyr (zhitomir).
