# 1125 German royal election

The 1125 German royal election was the Imperial election which lasted from 24 August to 1 or 2 September 1125, following the death of Henry V. It resulted in the coronation of the Duke of Saxony Lothair of Supplinburg as the King of the Romans by the Archbishop of Mainz, Adalbert on 13 September in Aachen.

## Sources

The events during the election are preserved in most detail in the Narratio de electione Lotharii Saxoniae ducis in regem Romanorum (Account of the Election of Lothair of Saxony as King of the Romans), which was written by an unknown eye-witness, probably a monk at Göttweig Abbey, where the manuscript of the text was found. The manuscript was produced in the middle of the 12th century and thus at least twenty-five years after the events it describes. The detailed content of the account and the author's unawareness of the conflict between Lothair and the Staufen brothers Frederick II and Conrad III indicates that the original text was written before the end of 1125 and that the surviving manuscript must be a copy of it. Further accounts of events during the election are provided by the Orderic Vitalis and Otto of Freising.

## Background

Archbishop Adalbert, advisor of the last Salian emperor Henry V, came into opposition to him during the Investiture Controversy by 1112 at the latest and made contact with the Saxon dukes who were opponents of Henry. Adalbert was imprisoned for three years and then continued his opposition to Henry V until he was compensated by the Emperor in the Concordat of Worms in 1122. Lothair remained an open enemy of the Salians and the Staufens.
Henry V died on 23 May 1125. His will left his personal property to his nephew Duke Frederick II von Staufen of Swabia, but placed the Imperial regalia in the care of his wife Empress Matilda at Trifels Castle until an imperial election could be held. As Archchancellor and highest-ranking prince of the Empire, Archbishop Adalbert I was in charge of preparing and presiding over the election. At Henry's funeral, which probably took place in Speyer in June, the anti-Salian attitude of Adalbert became clear. He desired a free election in which Duke Frederick II's succession would not be a foregone conclusion. Otto von Freising and Ordericus Vitalis report that Adalbert took the Imperial regalia from Matilda in preparation for the Imperial election.

## Candidates

The electoral system chosen by Adalbert was a recent innovation, first used in the election of the Abbot of Zwiefalten Abbey in 1095, which was called the Electio per compromissum (Election through compromise), in which there would be ten candidates from each of the provinces of Bavaria, Swabia, Franconia, and Saxony and they would all have to reach an agreement on a single candidate. The forty electors obviously could not agree, but three candidates were put forward:
* Frederick II, Duke of Swabia,
* Lothair III, Duke of Saxony, and
* Leopold III, Margrave of Austria
Otto von Freising records a fourth candidate, Charles I, Count of Flanders, who rejected the offer.
Frederick, as nephew, supporter and personal heir of the last Salian emperor could claim the strongest right to the throne and was considered the favourite. But the powerful Duke Lothair had significant support, as a long-term opponent of the Salian emperors' hostile policy toward the spiritual princes of the empire. Leopold of Austria was also linked to the Salian dynasty, since his wife Agnes of Waiblingen was a daughter of Henry IV, and he enjoyed the support of the southern German clergy.

## Course of the election

Frederick, who was encamped outside the city of Mainz, did not immediately appear at the electoral assembly. After the three candidates had been named, Adalbert went to Lothair and Leopold to ask if either of them was willing to recognise one of the other candidates as king. Both agreed and simultaneously announced their renunciation of their candidature. In this way, they showed their humility and demonstrated that they were worthy of being elected as king. According to the Narratio, Frederick believed that as a result of this announcement by the other two candidates, he was the only candidate remaining. The following day he entered the city victoriously, expecting to be elected by the assembled princes.
After Frederick's arrival, Adalbert repeated the question he had asked the previous day to each candidate, but when he came to Frederick he also asked whether he was willing to renounce the designation of a successor in order to enable free elections in future. Frederick left this question unanswered and went back to his camp to consult with his associates, thereby resigning as a candidate.
Subsequently, Lothair's followers riotously proclaimed him king and called on the inhabitants of the city who were assembled outside to celebrate the new king. Although many of the Bavarian princes protested at the elevation of Lothair to the kingship without an election and were demanding that an actual vote take place, Adalbert barred the doors to prevent the people of Mainz from acclaiming Lothair and to prevent the Bavarian princes from holding the vote. Then one of the Papal legates in attendance called for quiet and the Bavarian bishops declared that they could not reach a decision without Henry the Black, their Duke, who had left the assembly at the same time as Frederick II.
Perhaps three days later, the electors gathered once more and Lothair was elected king by the princes, including Henry the Black, who was present this time. The princes then performed homage to the new king. Frederick II finally did homage two days later and Archbishop Frederick of Cologne crowned Lothair in Aachen on 13 September. Conflict had already broken out between the king and Frederick II by the end of the year.
