Boļeslavs Sloskāns (Belarusian: Баляслаў Слосканс, 1893-1981) was a Latvian Roman Catholic bishop and a survivor and memoirist of the Soviet Gulag.

He served an additional two years in prison until he was repatriated to Latvia on 22 January 1933 in exchange for an accused Soviet spy in the custody of the Latvian government.

[2] Pope Pius XI appointed Bishop Sloskāns an assistant to the Papal Throne on 5 April 1933 in recognition of the harsh treatment he had experienced while imprisoned.

[3] Returning to Latvia, Bishop Sloskāns continued to serve as the apostolic administrator of Mohilev and of Minsk in absentia while he took charge of the Roman Catholic seminary in Riga.

In 1947 Bishop Sloskāns moved to the Benedictine Abbey of Mont César in Leuven[4] at the invitation of the local Belarusian émigré community.

In December 2004, Bishop Sloskāns was declared Venerable by Pope John Paul II, and an investigation was opened for potential Beatification and Canonization.

[9][10][11] In 2012, several days long commemorative events dedicated to Boļeslavs Sloskāns were held in Mahiliou with the participation of senior Catholic clergy from Belarus and Latvia.
