'Mark of Križevci') was a Croatian Roman Catholic priest, professor of theology and missionary, who was active in the 17th century.

Cardinal Péter Pázmány, Archbishop of Esztergom (then living in Nagyszombat – present-day Trnava – because of the continuing Ottoman occupation of much of Hungary), called him from Zagreb and appointed him both rector of the local seminary and canon of the cathedral chapter.

[4] In early 1619, Krizin was sent to administer the estate of the former Benedictine Abbey of Széplak, near Kassa, Hungary (now Košice, Slovakia).

Around the same time, the Calvinist Prince of Transylvania, Gábor Bethlen, led a nationalist uprising against the Austrian Habsburgs, who then ruled Hungary.

[5] In September 1619, the city came under siege by the forces of the commander of the Calvinist army, George I Rákóczi.

At that time Marko was staying at the then-Jesuit Church of the Holy Trinity, in the company of the two Jesuits ministering to the Catholics of the city.

[7] The remains of the Košice martyrs now rest in various locations, including the Basilica of Esztergom and the Ursuline Church of St. Anna in Trnava.
