The Electorate of Cologne (), sometimes referred to as Electoral Cologne (), was an ecclesiastical principality of the Holy Roman Empire that existed from the 10th to the early 19th century. It consisted of the Hochstift — the temporal possessions — of the Archbishop of Cologne, and was ruled by him in his capacity as prince-elector. There were only two other ecclesiastical prince-electors in the Empire: the Electorate of Mainz and the Electorate of Trier. The Archbishop-Elector of Cologne was also Arch-chancellor of Italy (one of the three component titular kingdoms of the Holy Roman Empire, the other two being Germany and Burgundy) and, as such, ranked second among all ecclesiastical and secular princes of the Empire, after the Archbishop-Elector of Mainz, and before that of Trier. The capital of the electorate was Cologne. Conflicts with the citizens of Cologne caused the Elector to move to Bonn. The Free Imperial City of Cologne was recognized after 1475, thus removing it from even the nominal secular authority of the Elector. Cologne and Bonn were occupied by France in 1794. The right bank territories of the Electorate were secularized in 1803 during the German mediatization. The Electorate should not be confused with the Roman Catholic Archdiocese of Cologne, which was larger and included suffragan bishoprics such as Liège and Münster over which the Elector-Archbishop exercised only spiritual authority (see map below). History Cologne was the ancient Roman city of Colonia Agrippina in the province of Germania Inferior, and has been a bishop's see since Roman times. In 953, the archbishops of Cologne first gained noteworthy secular power, when Bishop Bruno was appointed as duke by his brother Emperor Otto I. To weaken the secular nobility, who threatened his power, Otto endowed Bruno and his successors in the bishop's see with the prerogatives of secular princes. This was the beginning of the electoral state of Cologne. It was formed from the temporal possessions of the archbishopric and included in the end a strip of territory along the left Bank of the Rhine east of Jülich, and the Duchy of Westphalia on the other side of the Rhine, beyond Berg and Mark. By the end of the 12th century, the Archbishop of Cologne was one of the seven electors of the Holy Roman Emperor. Besides being prince-elector, he was Arch-chancellor of Italy as well, technically from 1238 and permanently from 1263 until 1803. In
