Hasselburg is located in the northwest of the German state Saxony-Anhalt, on the northern edge of the Flechtinger ridge . The district is 1.9 kilometers away from Flechtingen Ort and is surrounded by agricultural areas that drive a wedge up to two kilometers wide into the Flechtinger Forest in an easterly direction. In the north are the Calvörder Forest and the Calvörder Mountains . Hasselburg is 98 meters above sea level.
The village, which always has fewer than 200 inhabitants, has belonged to the Brandenburg margraves since the 14th century , but became the property of the Archbishopric of Magdeburg in the 16th century . After its secularization in 1680, the Duchy of Magdeburg and from 1701 Kingdom of Prussia took over rule. Between 1806 and 1813 the place was under the rule of the Napoleonic Kingdom of Westphalia under Jérôme Bonaparte and was assigned to the canton of Calvörde . After the Wars of Liberation, Prussia carried out an administrative reform with which Hasselburg was assigned to the Gardelegen district .
The noble Schenk von Flechtingen family ran an estate in Hasselburg until 1820. Afterwards she sold it to the barons von Spiegel to this mountain. In 1870 they built a manor house known as the Hasselburg Hunting Lodge , which they did not live in themselves, as the Spiegels had long been resident in Halberstadt as canons and also had their summer residence in nearby Seggerde . They only used the Hasselburg manor house for hunting, from which the name "hunting lodge" goes back. Otherwise it served as accommodation for the estate manager. Between 1854 and 1880 the Counts of Alvensleben were landlords, after which the property reverted to the Barons of Spiegel. After Werner Friedrich Julius Stephan von Spiegel's death , his wife signed the estate over to her brother-in-law Eduard von Davier in 1890, whose descendants were lords of the Hasselburg estate until 1945. Especially under his son Karl von Davier, the estate developed into an exemplary modern farm at the turn of the century. In 1910, the manor district, which was administratively independent at the time, had 64 inhabitants, while the Hasselburg municipality had only 44 inhabitants. On September 30, 1928, the Hasselburg manor district was merged with the Hasselburg rural community. In 1933 the population of the community had increased to 199.
Towards the end of the Second World War, Hasselburg came into the territory conquered by the US Army in early 1945, but was handed over to the Soviet occupation zone on July 1, 1945 . In the same year, the Soviet occupation authorities ordered a land reform , with which the last landlord, Volrath von Davier, was expropriated and the land was given to new farmers. The manor house was taken over by the community and subsequently used as a library, nurses station, sales point, restaurant and residential building. With the GDR territorial reform of 1952, Hasselburg became part of the Haldensleben district . In the course of the nationalization of GDR agriculture, an agricultural production cooperative (LPG) was founded in Hasselburg by previously private farmers in the early 1950s . Up to 1960 there were still six privately run farms in the village, but they were forced to join the LPG by the end of the year. In 1964 Hasselburg had 245 inhabitants. On January 1, 1972, the place was incorporated into the municipality of Flechtingen.
