Electorate of Trier

The Electorate of Trier (Kurfürstentum Trier or Kurtrier) was an ecclesiastical principality of the Holy Roman Empire that existed from the end of the 9th to the early 19th century. It consisted of the temporal possessions of the prince-archbishop of Trier (Erzbistum Trier), also prince-elector of the empire. The capital of the electorate was Trier, with the main residence of the Elector being Coblence from the 16th century onward. The electorate was secularized in 1803 during Napoleonic rule.

The Elector of Trier, in his capacity as archbishop, also administered the archdiocese of Trier, whose territory did not correspond to the electorate (see map below).
