Origins

The origin of the Kirchbergs and their early genealogy cannot be taken seriously historically. The frequent use of the first names Otto and Hartmann could indicate family ties to the Counts of Buchhorn, a branch of the Udalrich line that was wealthy on Lake Constance and had died out in 1089 , or to the Hupaldings. A Hartmann is mentioned in 980 as Gaugraf im Illergau. The first documented mention is in 1087, when an Otto de Chirchperg testifies to a donation to the Salvator monastery in Schaffhausen. The foundation and rich endowment of the Wiblingen Abbey in 1093 by the brothers Otto and Hartmann from Kirchberg shows the financial possibilities of the Kirchbergs at that time. The Wiblingen monastery remained the burial place of this noble family until the Kirchbergs died out.

Domain

The County of Kirchberg was an imperial fiefdom that arose from the eastern parts of the former Rammachgau. The area can be described as an irregular square, the northern border of which is formed by the Danube river from the confluence of the Roth upstream to about Obermarchtal , the eastern border originally probably by the Roth , later by the Iller and the western border by the Riss and the upper reaches of the Schussen. The cornerstones of the irregular southern border are Boos in the south-east, the lower reaches of the Aitrach in the south and the area south of Schussenried in the southwest. In this area, the Kirchberg family had the County rights to rule, enjoyed the corresponding rights of use and had the wildlife sanctuary. Their allodial holdings were concentrated between the Rot and Roth, but also lay partly north of the Danube and east of the Roth. In the High and Late Middle Ages, parts of it went as subfiefs or fiefdoms to the local lower nobility and to the citizens of Ulm.

Divisions of the Kirchberg family

In the High Middle Ages, probably still in the 12th century, the Kirchbergs split into two, and in 1250 finally into three lines. The reasons for the first division are not documented.

• Kirchberg-Kirchberg: The main line retained its headquarters in Oberkirchberg and the rights of the counts. Count William I died in 1366. His daughter Agnes had been married to Ulrich IV, Lord of Matsch since 1346 and brought her inheritance into this marriage. Parts of the Kirchberg family estate went to this powerful aristocratic family, wealthy in Vinschgau, Engadin, Veltlin and Graubünden, who soon bought the remaining part, the dowry from William I's sister Bertha. As a result, the House of Matsch also temporarily held the additional title of Count of Kirchberg.
• Kirchberg-Brandenburg: Southwest of this is the rule of Kirchberg-Brandenburg. Their center of power was in Dietenheim, which received city rights as early as 1280. From their family castle (probably Regglisweiler Castle) only overbuilt ditches are preserved. The branch seem to have been the most politically active line; representatives of this family appear on royal charters several times. The first documentary evidence of a Kirchberg-Brandenburg (Count Otto) dates to 2 February 1239. According to the chronicle of the Imperial Abbey of Rot (Roth) on the Rot, the line could have split off even earlier. After the serious wounding of Count Hartmann VI in the Battle of Oberndorf (17 April 1298) the Brandenburg estates were confiscated by Albert I of Germany and passed on without regard to the inheritance claims of the surviving Kirchbergs, first to the knights of the Ellerbach family. The last of this branch was abbot Conrad, from the monastery of Allerheiligen/Schaffhausen, who died on 12 March 1322 (1323).
• Kirchberg-Wullenstetten: This line originated in 1250 from an inheritance division made by the brothers Conrad II and Eberhard III. Eberhard was the founder of the Wullenstetten line. His possessions were mainly to the right of the Iller. On 25 January 1322, Eberhard's son, Count Conrad the Elder, was named as having his seat in Wullenstetten. It is possible that the Wullenstetten line became the administrators of the Kirchberg part that had been annexed by the Matsch family and was then returned to the original family. They resided in the family castle on the Oberkirchberg. Kirchberg-Wullenstetten line was able to get back the old Kirchberg possessions as a pledge in 1390; Finally, in 1434, Eberhard von Kirchberg-Wullenstetten was enfeoffed again by Sigismund, Holy Roman Emperor with the county, so that large parts of the Kirchberg family estate came back into the hands of the family.

Extinction of the family

The last representatives of the count's family were the two cousins William (died around 1489) and Philip from the Wullenstetten line, who shared the inheritance. Both were heavily in debt. William, who was apparently from 1473 personal servant of Eberhard V, Count of Württemberg-Urach,^[3] sold his half in 1481 to George, Duke of Bavaria-Landshut, and Philipp in 1498. Duke George was already in possession of the dominions of Weissenhorn and Pfaffenhofen bordering to the east. After George's death in 1503 and the beginning of the Landshut War of Succession , King Maximilian I.the lordships and pledged them in 1507 for the very large sum of 50,000 guilders to the Fuggers , who called themselves Count of Kirchberg and Weisenhorn after being elevated to the hereditary imperial count (1526).^[4] Philip had retained some of his Kirchberg estates until his death on August 20, 1510. In November 1510, his daughter and heiress Apollonia and her husband, John, Count of Montfort-Tettnang, sold the Wain estate they had acquired in 1499 .
