ENThe success of Russia in the war against the Grand Duchy of Lithuania in the middle of the 17th century was followed by the occupation of a large area of the Grand Duchy of Lithuania. The invader’s intention to strengthen its influence in the conquered territory resulted in introducing changes in the political system of Lithuania. As a result, a new judicial organization was established between 1655 and 1656, however, it was not unified across the whole country. The Russian authorities established in Vilnius at that time coexisted with the Lithuanian judicial system. The aim of this study is to present their organization and functioning since their establishment until the liberation of the city in 1660. A historical and legal method was applied in this research.
