After the Insurrection of 1863, the diocese saw all its religious violently expelled. The monasteries were converted into barracks, the churches given to the Orthodox or the secular clergy, the libraries dispersed, the possessions of the religious confiscated. In 1910 there remained only one monastery of Benedictine Sisters (connected with the Church of St. Catherine at Vilnius) with six septuagenarian nuns, a Bernardine convent at Slonim with four septuagenarian nuns, a Franciscan monastery at Grodno with a single friar and in the same city a convent of Brigittine Sisters with two religious.
