 As the Russian Empire gained the territories along its western frontier through a series of wars and Partitions of Poland that lasted from the seventeenth through the end of the eighteenth centuries, the Uniate Church was partly incorporated into the state Russian Orthodox Church, and in 1839 abolished altogether by the act of the Synod of Polotsk.However, the latter event did not affect the Eparchy of Chelm.Thus after the November Uprising in 1831, the Synod of Polotsk which disestablished the Uniate church outside the Kingdom of Poland did not affect Eparchy of Chełm.
