Today Calenberg Land covers a geographical area of about 20 x 30 km. It lies on the left bank of the river Leine and is bordered to the west by the hills of the Deister, Kleiner Deister and Osterwald. Its northern boundary is Hanover and the line of the A 2 motorway towards Wunstorf. Its name is not derived from the hill known as the Kalenberg on the Deister. The region includes the Calenberg Loess Börde which was formed during and after the Weichselian glaciation. Strong north winds deposited the loess soil in layers between 0.2 –2 m thick, the upper layers of which became loam. The area is heavily dominated by arable farming as a result of its fertile soils. The elevations of the Marienberg, crowned by Schloss Marienburg, Süllberg, Benther Berg, Gehrdener Berg and Stemmer Berg dominate the otherwise gently rolling hills. Under the Calenberg Land lie natural resources which were already being used in the Middle Ages. There are coal deposits in the Deister, potash salts, which were mined at Ronnenberg and Benthe, sandstone and limestone in the Deister and Kleine Deister, clay for baking bricks and sand and gravel in the river terraces of the Leine.

The towns of the Calenberg Land developed in the Middle Ages as the ruling classes conferred self-administration and market rights. All of them remained farming towns, in which many of the inhabitants continued to work on the land. Whilst today the majority of population of the Calenberg Land commutes into Hanover, Hanover's citizens use the region as their local recreation area.
History
The present-day geographical region of Calenberg Land roughly corresponds to the Germanic area of Marstemgau which was ruled by the House of Billung in the Early Middle Ages. In the 12th century various fiefdoms emerged ruled by noble families from the region who were enfeoffed by the bishops of Minden and Hildesheim. These were the counts of Wölpe, of Roden, of Schaumburg, of Schwalenberg, of Spiegelberg and of Hallermund. At that time the counts founded a number of abbeys including: Mariensee, Marienwerder, Barsinghausen, Wennigsen and Wülfinghausen. In the 13th century the House of Welf gained the upper hand in Calenberg Land, although it was not called that. They bought out the counts and their estates or defeated their feudal masters in the shape of the bishops of Hildesheim and Minden. In the 13th century the Welfs built, south of Hanover in the vicinity of the Leine the water castle of Calenberg. Out of that emerged the Welf sub-principality of Calenberg. In this way the land ruled by the Principality of Calenberg emerged, which was formerly much larger than the Calenberg Land is today. In the 15th century it stretched as far north as Nienburg/Weser and as far southwest as Hamelin. In 1495 the Principality of Calenberg was united with the Principality of Göttingen to become the Principality of Calenberg-Göttingen. In 1519, during the Hildesheim Feud, there was serious devastation in the region. A map published in 1590 depicts almost all the settlements in the Calenberg Land as burning. In 1542 the area became Lutheranthanks tothe work of the widowed duchess, Elisabeth of Brandenburg, and Anton Corvinus carried out the Reformation at her request. An attempt to re-catholicise the area by Eric II, Duke of Calenberg during the Schmalkaldic War failed due to popular resistance. In 1625, during the Thirty Years War, the forces of Tilly invaded and captured the castle of Calenberg after a three-week siege. The general ruled the whole of the Calenberg Land with the exception of Hanover. Not until 1633 was the castle recaptured. Calenberg Land was incorporated into the Landdrostei, later Regierungsbezirk of Hanover in 1823 together with Hoya and Diepholz. After the dissolution of the Regierungsbezirke and their governments in Lower Saxony in 2004 it became part of Hanover Region. Since the 19th century there has been an economic boom in the Calenberg Land as a result of more intensive use of its geological and agricultural resources, such as potash mining and intensive sugar beet farming by cement factories and sugar refineries respectively.
