The Diocese of Aachen is located in the extreme west of the state of North Rhine -Westphalia. It borders on the German side of the Archdiocese of Cologne and at the bishoprics of Münster, Essen and Trier. On the Dutch side there are common boundaries with the Diocese of Roermond, on the Belgian side of the diocese of Liege.


Already at the beginning of the 19th century, there was for a short time Diocese of Aachen. Its history is dominated by the power politics of Napoleon, and the reactions of the Holy See. Outfitted it was built in 1802 by Napoleon, who composed it from the left bank area of the Archdiocese of Cologne as well as parts of the diocese of Liège and smaller parts of the dioceses of Utrecht, Roermond and Mainz. In 1808 it was further extended to include the area around Wesel. The first bishop was Marc- Antoine Berdolet, the Napoléon appointed. After the death Berdolets (13 August 1809) rose Napoléon Jean -Denis- François Camus, called Le Camus, to succeed, but this was not an endorsement of the Vatican. Thus, Pope Pius VII wanted to show the limits of the authority of the emperor. After the end of French rule, the diocese was dissolved again by the pope with the Bull De salute animarum on July 16, 1821 de jure and incorporated into the Archbishopric of Cologne. The final resolution of the first bishopric of Aachen was then carried out on 24-25. March 1825 after the last meeting of the Chapter.

The present Diocese of Aachen was built over a hundred years later, on August 13, 1930. First, the Prussian Concordat between the Holy See and the Free State of Prussia was closed in 1929, signed by Nuncio Pacelli, the future Pius XII. , And the Prussian Prime Minister Otto Braun. By the papal bull " Pastoralis officii nostri " on August 13, 1930 and the "Decree of the Apostolic Nuncio in Germany, Re Domkapitel Circumscripto the Diocese of Aachen " the reconstruction was completed. Joseph Heinrich Peter Vogt was ordained a bishop.


In recent years, a process of consolidation of parishes and the formation of pastoral care units in the Diocese of Aachen was initiated. The background is the declining numbers of priests and parishioners and the resulting austerity measures.
