The diocese was first created as Apostolic Administration of Trnava on 29 May 1922, subordinate to the
Holy See, on the territory of
Archdiocese of Esztergom which became part of the
Czechoslovakia after 1918. On the order of
Pope Paul VI on 30 December 1977, it was elevated to the status of metropolitan archdiocese and renamed to the Archdiocese of Trnava, and it had at first
suffragans of
Nitra,
Banská Bystrica,
Rožňava,
Košice and
Spiš. On 31 March 1995, the archdiocese was renamed to Archdiocese of Bratislava-Trnava, and since then it had only suffragans of Banská Bystrica and Nitra. Its territory covered Bratislava, Trnava,
Nitra (except the city of
Nitra and the strip connecting it with the main part of the
Diocese of Nitra), small part of the
Trenčín and south-western part of the
Banská Bystrica regions. As of 2004, it covered an area of approximately 14,000 km² with a population of 1,930,000 people of which around 70% were of Catholic faith. On 14 February 2008, the archdiocese was split between several dioceses. Trnava became seat of the newly created Archdiocese of Trnava, which, despite being an archdiocese, belongs to the ecclesiastical province of
Bratislava as its suffragan. Other parts of the former diocese have been split between the dioceses of
Nitra and
Banská Bystrica (see e.g. this map (in Slovak).
Róbert Bezák, C.SS.R. (a member of the
Redemptorist order) served as archbishop from 2009. In January 2012, the Vatican had named the Czech bishop
Jan Baxant as its apostolic visitor to the archdiocese of Trnava. Archbishop Bezák's removal from this see was announced 2 July 2012. ==Bishops==
