Imperial election in the context of Matthias (HRR)

The prince-electors (German: Kurfürst [ˈkuːɐ̯ˌfʏʁst] , pl. Kurfürsten [ˈkuːɐ̯ˌfʏʁstn̩] , Czech: Kurfiřt, Latin: Princeps Elector) were the members of the Electoral College of the Holy Roman Empire, which elected the Holy Roman Emperor. Usually, half of the electors were archbishops.

From the 13th century onwards, a small group of prince-electors gained the privilege of electing the King of the Romans. The king would then later be crowned Emperor by the pope. Charles V (elected in 1519) was the last emperor to be crowned (1530); his successors assumed the title "Elected Emperor of the Romans" (German: erwählter Römischer Kaiser; Latin: electus Romanorum imperator) upon their coronation as kings.

The imperial election of 1519 was an imperial election held to select the emperor of the Holy Roman Empire. It took place in Frankfurt on 28 June, Charles V was elected and crowned Holy Roman Emperor the next year.

This article lists the Margraves and Electors of Brandenburg during the time when Brandenburg was a constituent state of the Holy Roman Empire.

The Mark, or March, of Brandenburg was one of the primary constituent states of the Holy Roman Empire. It was created in 1157 as the Margraviate of Brandenburg by Albert the Bear, Margrave of the Northern March. In 1356, by the terms of the Golden Bull of Charles IV, the Margrave of Brandenburg was given the permanent right to participate in the election of the Holy Roman Emperor with the title of Elector (German: Kurfürst).

The Electoral College (German: Kur; Latin: Collegium Electorale) of the Holy Roman Empire was the gathering of prince electors for an imperial election, where they voted for the next King of the Romans and future Emperor. The German name of this gathering, Kur, is derived from the Middle High German kur or kure ("election").

Initially all the so-called "great ones of the Empire" (Große des Reiches) were entitled to vote, but by the second half of the 13th century, only the prince electors were entitled to participate in the royal election.

Frankfurt was a major city of the Holy Roman Empire, being the seat of imperial elections since 885 and the city for imperial coronations from 1562 (previously in Free Imperial City of Aachen) until 1792. Frankfurt was declared an Imperial Free City (Freie und Reichsstadt) in 1372, making the city an entity of Imperial immediacy, meaning immediately subordinate to the Holy Roman Emperor and not to a regional ruler or a local nobleman.

Due to its imperial significance, Frankfurt survived mediatisation in 1803. Following the collapse of the Holy Roman Empire in 1806, Frankfurt fell to the rule of Napoleon I, who granted the city to Karl Theodor Anton Maria von Dalberg; the city became known as the Principality of Frankfurt. The Catholic cleric Dalberg emancipated Catholics living with the city boundary. In 1810 Dalberg merged Frankfurt with the Principality of Aschaffenburg, the County of Wetzlar, Fulda, and Hanau to form the Grand Duchy of Frankfurt. After the defeat of Napoleon and the collapse of the Confederation of the Rhine, Frankfurt was returned to its pre-Napoleonic constitution via the Congress of Vienna of 1815 and became a sovereign city-state and a member of the German Confederation.

Queen of the Romans (Latin: Regina Romanorum, German: Königin der Römer) or Queen of the Germans were the official titles of the queens consort of the medieval and early modern Kingdom of Germany. They were the wives of the King of the Romans (chosen by imperial election), and are informally also known as German queen (German: Deutsche Königin). A Queen of the Romans also became Holy Roman Empress if her husband was crowned Holy Roman Emperor, in the Middle Ages usually by the Pope in Rome during an Italienzug. Most elected Kings of the Romans did, but some never made it that far, and thus their wives only ever achieved the status of Queen of the Romans.

Empress Maria Theresa (1745–1780) is often considered to be a ruler in her own right, as she was Queen regnant of Bohemia and Hungary, and although her husband Francis I was crowned Holy Roman Emperor in 1745, it was she who ruled the Empire and continued to do so even after Francis' death in 1765 before ruling jointly with her son Emperor Joseph II.

An imperial election was held in Frankfurt on 28 November 1562 to select the emperor of the Holy Roman Empire.
