The Apostolic Nunciature to Bavaria was an ecclesiastical office of the Roman Catholic Church in Bavaria. It was a diplomatic post of the Holy See, whose representative was called the Apostolic Nuncio to Bavaria, a state – consecutively during the nunciature's existence – of the Holy Roman Empire, of its own sovereignty, and then of Imperial, Weimar and finally Nazi Germany. The office of the nunciature was located in Munich from 1785 to 1936. Prior to this, there was one nunciature in the Holy Roman Empire, which was the nunciature in Cologne, accredited to the Achbishop-Electorates of Cologne, Mainz and Trier.
A new nunciature was established by Pope Pius VI in Munich in 1785, requested by Charles Theodore, Elector of Bavaria. The appointment of Giulio Cesare Zoglio as nuncio angered the archbishop-electors of Cologne, Mainz, and Trier, who considered the Nuncio to Cologne to be competent for all the Empire.Joseph II, Holy Roman Emperor sided with the electors, and declared he would recognise nuncios in their "political character" only. Thus, there were two nuncios: one in Cologne, and one in Munich, the division of whose jurisdictions was a matter of contention.
With the Archbishop-Electorates of Cologne, Mainz, and Trier occupied by France and dissolved in 1795 and 1803, respectively, the last nuncio to Cologne, Annibale della Genga, had to reside in Augsburg, which was annexed to Bavaria in 1803. With the dissolution of the Empire in 1806 Bavaria gained full sovereignty, and the tradition of the nuncio to Cologne was continued by the nuncio to Austria in Vienna, competent for the Empire of Austria only.
