Find aids: Find book from 1990 (online searchable); partly unexcavated registry formers: Walbeck belongs to the city of Hettstedt, Lkr. Mansfeld-Südharz, Saxony-Anhalt. In 992 Otto III from Wittum transferred the royal court of Walbeck to Empress Adelheid of Quedlinburg to establish a Benedictine monastery consecrated in 997. In 1540/42 the Counts of Mansfeld secularised the monastery over which they had exercised the bailiwick since 1387. During the sequestration in 1570/73, Walbeck was placed under the administration of the Electorate of Saxony as part of the county of Mansfeld-Vorderort. In 1815, it passed to Prussia, where it was assigned to the province of Saxony in 1816-1945. In 1563 Count Hans Albrecht von Mansfeld-Vorderort pledged the Walbeck office, consisting of the monastery estate and the villages Ritterode and Meisberg, to Ludolf von Bortfeld. His descendants ceded the pledge in 1661 to Count Johann Albrecht von Ronoff, who in 1663 compared himself with the Mansfeldern on resale acquisition. In 1677 he sold it to Friedrich Casimir zu Eltz. In 1727 the estate passed from his descendants by inheritance to Philipp Wilhelm and Johann Clamor von dem Bussche. The latter acquired it in 1742 as a hereditary purchase, in 1745 achieved the status of a knight's manor with old written records, and in 1743/50 had the baroque palace built. In 1845 Walbeck fell to Friedrich August Tellemann, who had married Anna von dem Bussche, by buying out the remaining heirs. Through her daughter Anna's marriage to Heinrich Friedrich Remigius Bartels, the manor was transferred to his family, who owned it until it was expropriated in the course of the land reform in 1945. In 1827 the patrimonial jurisdiction over Walbeck, Ritterode, Meisberg (partly) and Quenstedt belonged to the manor called Rittergut. The Quenstedt manor, formed from several hereditary properties, was acquired in 1726/27 and separated again in 1843 when it was divided, and the Kupferberg manor, which had belonged to Walbeck since 1667, before Hettstedt, was temporarily co-administered. The church of Walbeck was supplied by the parish of Bräunrode. Inventory information: On the basis of a contract concluded in 2014, the holdings will be deposited in the Saxony-Anhalt State Archives.

The Langenapel, founded in the course of the eastern colonisation of the 12th/13th century, was located in the Altmark, which developed into a territory in the 13th/14th century and finally came under the sovereignty of the Electors of Brandenburg in 1449. In 1816 the Altmark became part of the Prussian province of Saxony, which existed until 1945. For 1375 a Brandenburg castle in the possession of the von Crucemann family is documented in Langenapel. In the early 15th century, the castle fief of Salzwedel Castle passed to the Knesebeck family (black line), who, in 1425/33, brought the entire village to themselves through exchange contracts with the Schulenburg family. A storming by the citizens of Salzwedel in 1443 and an opening treaty of 1469 deprived the castle of its military significance. However, in the late 15th century the Chancellery of Kurbrandenburg counted the Knesebecks on Langenapel among the exclusive circle of the feudatories of the castle. The manor, which had been converted from a castle into a state manor, remained in family ownership until its expropriation in the course of the land reform in 1945. In 1842, the manor included patrimonial jurisdiction and the church patronage over Langenapel, which was parsed after Easter Sole. The property complex also included a manor in Dähre, acquired in 1544, and a fortification in Lagendorf that was documented in 1616. Around 1897, the Knesebeck family acquired the Deutschhorst manor from the von Meding family, the manor archive of which was incorporated into the collection. Inventory information: The archive of the Langenapel estate of Knesebeck was seized by the priest Dr. Nötzel in Osterwohle and taken over by the Saxony-Anhalt state archives in Magdeburg in 1948. As the holdings had signatures, the old structure was restored according to the signatures. The order and recording of the archive records as well as the creation of a register took place in 1952. The retroconversion of the present finding aid register was carried out in October 2013. On the basis of a contract concluded in 2008, the holdings will be deposited in the Saxony-Anhalt State Archives.

In the late Middle Ages, Eichenbarleben was a fief of the Archbishopric of Magdeburg, which fell to the Electors of Brandenburg in 1680 as the Duchy of Magdeburg and merged in 1816 into the Prussian province of Saxony, which existed until 1945. 1140 a count Hoyer created the basis for a noble seat in oak bar life by the acquisition of 12 hooves. Since 1283 ministerials of Eichenbarleben are provable. In 1452 the castle, known as the Magdeburg fief, which belonged to the von Wanzleben family, passed to the von Alvensleben black line at Hundisburg. Since 1565 Eichenbarleben has been the seat of its own family branch. In 1813 he had to sell the estate, but it remained in family hands and belonged to the line Erxleben II since 1821. After the death of the Prussian Minister of State Count Albrecht von Alvensleben in 1858, Eichenbarleben moved to the von Krosigk family, who owned the estate until its expropriation in the course of the land reform in 1945. The manor, which was described in 1842 as fit for state parliament, included the parish patronage and the patrimonial jurisdiction over Eichenbarleben and Süplingen. Inventory information: The holdings seized in the course of the land reform were handed over to the then State Archives of Magdeburg in October 1949. An incomplete distortion list did not show any inner order. As a result, the inventory was redrawn. Additional information: Literature: aristocratic archives in the Saxony-Anhalt state archives.
