Blessed Anton Martin Slomšek (26 November 1800 – 24 September 1862) was a Slovene Roman Catholic prelate who served as the Bishop of Lavant from 1846 until his death.

He served in various parishes as a simple priest prior to his becoming a bishop in which his patriotic activism increased to a higher degree since he advocated writing and the need for education.

He penned textbooks for schools including those that he himself opened and he was a vocal supporter of ecumenism and led efforts to achieve greater dialogue with other faiths with an emphasis on the Eastern Orthodox Church.

[1][3] He underwent his theological and philosophical studies since 1821 (a classmate was the poet France Prešeren) in order to enter the priesthood and he was later ordained as such on 8 September 1824 in Klagenfurt.

In one of his final appointments, Pope Gregory XVI, made Slomšek the new Bishop of Lavant and he received his episcopal consecration a couple of months later in Salzburg, although he did not celebrate his formal installation until September 1859, when he first moved to his new see.

[1] He also wrote songs and some of which (like the toast "En hribček bom kupil") achieved great social standing and some are still sung at present.

Pope Pius IX entrusted him with the mission to renew the religious life in Benedictine monasteries and so he made a series of apostolic visits to see these places.
