On Tuesday 20 November 2012, according to biographical information in a press release from the Holy See Press Office's Vatican Information Service (VIS), Pope Benedict XVI appointed Auxiliary Bishop Marián Chovanec of the Roman Catholic Diocese of Nitra (based in Nitra, Slovakia), Titular Bishop of Massita, as Bishop-elect of the Roman Catholic Diocese of Banská Bystrica.

Bishop Chovanec was born on 16 September 1957 in Trenčin, Slovakia, a part of the Diocese of Nitra.

He was expelled from the Seminary in Bratislava, Slovakia, because he had refused to cooperate with the Government-backed Association "Pacem in Terris" (Peace on Earth).

On 30 December 1977, it was taken from the former and became part of the newly created Slovak ecclesiastical province with metropolitan being the Diocese of Trnava, which was renamed on 31 March 1995 to the Archdiocese of Bratislava-Trnava.

On the other hand, it gained former eastern areas of the Archdiocese of Bratislava-Trnava (from Banská Štiavnica to Šahy and Veľký Krtíš) (see e.g. this map (in Slovak), and some other border changes occurred as well.
