Otto III of Hachberg

Otto III. of Hachberg ( born March 6, 1388 Rötteln Castle, † November 14 1451 in Konstanz ) was from 1410 to 1434 Bishop of Constance. During this time he was the host of the Council of Constance ( 1414-1418 ).

Although the house Hachberg - Sausenberg belong there and actually Otto II, he is consistently in the historical literature as Otto III. out of Hachberg, since he was the third Bishop of Constance named Otto.

Otto was the eldest son of the Margrave Rudolf III. of Hachberg - Sausenberg and the Anne of Freiburg- Neuchâtel.

The bishop of Constance

Already 1403 - Otto was just 15 years old - he is known as a canon of Basel and Pope Boniface IX. interceded with the provost of Basel for petrol, with this as a reward for the about-face of his father, Rudolf III. , the anti-pope in Avignon, Benedict XIII. can be assumed for the Roman Pope. 1404 Otto is referred to in the registers of the University of Heidelberg as a cleric of the diocese of Constance and canon of Basel and Cologne.

In the former enterprising climate of the Roman Church also fit the 1409/1410 Rudolf III notarized negotiations. with the Bishop of Constance Albrecht Blarer about his resignation and the official handover to Otto in exchange for financial compensation. Here, the papal backing it was probably safe, as it was agreed if need be, against the resistance of the Constance cathedral chapter, the consent of a recognized Bishop Blarer Pope for assignment of the diocese sought.

On 11 July 1410, the tough negotiations have been completed and the cathedral chapter was its resistance to first. In December 1410, Otto received the confirmation of Antipope John XXIII .. On February 2, 1411 Otto took over the government of the diocese of Constance - he never received episcopal consecration.

Otto has to deal with the debt of the diocese, but had regard to the Council of Constance, which should start in 1414, to make structural changes to the Episcopal Palatinate. Construction of the St Margaret's Chapel probably followed in 1423 and later at Konstanz Cathedral. In general, Otto was as baufreudig and it was accused thereby have increased the debt of the diocese enormous.

In poor health, political and financial pressure put Otto in December 1424 his duties temporarily. The Chapter should manage the diocese by a deputy. In 1427 he wanted to take over the administration of the diocese again, the restart was burdened by a further dispute with the cathedral chapter, whom he caused by the deposition of high palpable diocesan official. It was not until 1429 he seems to have really taken back by the government. Already in 1431 escalated the continual struggle again with the cathedral chapter and Otto moved its headquarters even in the short term to Schaffhausen. The conflict employed even in 1432 the Council of Basel. Shortly after a positive for gasoline arbitration award, there was already the next conflict with the cathedral chapter. The Corpus Christi procession in 1432 turned out to Constance in a political demonstration with three competing processions. Again, the Council of Basel was busy with local disputes. The compromise found there deposed Otto partially. When Otto came in 1433 with Friedrich von Zollern in negotiations over a transfer of the bishopric, because he had health problems again, the chapter put across again. Again, the Council and papal commissioner had to deal with the conflict. On September 6, 1434 Otto was deposed as bishop of Constance and was Titular Bishop of Caesarea.

The private scholar

After his deposition, which is in the literature often called "resignation ", Otto built his already begun at the time of the council library by purchasing and commissioned copies heavily from. The complete collection of the Corpus Iuris Canonici and Roman legal literature demonstrate a focus of interest in canon law. Another emphasis was on the veneration of Mary.

In Otto's library also three codices were predominantly self-written treatises. This also includes the treatise De conceptione beatae virginis. Otto responded with a treatise on a Constance local debate between the Franciscans and the Dominicans joined him and was not at all involved in the debate at the Council of Basel and its decision on this issue. However, Otto sent this treatise for review to the Council scholar in Basel, although he stood in sharp contrast to their opposition to the Pope. In March 1446 John of Segovia Otto confirmed in opinion regarding the Immaculate Conception; original idea has spread in this or other documents, Otto.

After Otto's death ( in 1451 ) inherited his brother William his stately library ( 58 books ), which he in 1451 to the abbot of the monastery of Reichenau, Friedrich von Wartenberg, sold. Otto's estate so that was part of the famous Reichenauer library.
