Town divisions Besides the main centre of Kirchhain with about 8,300 inhabitants, 12 further constituent communities share another 8,900 people: History In prehistoric times a network of long-distance and connecting trails crossed back and forth over the area where the town of Kirchhain was later to be founded. Since the early New Stone Age, there is evidence of almost continuous settlement in the area through various epochs. The high point of the expansion of settlement was in the early Iron Age (5th century BC). The first territorial development however began only in the 12th century; in 1146 the settlement was first mentioned in a document under the name "Werphloh". The region belonged at that time to the landgravates of Thuringia and Hesse, whereas the neighbouring Amöneburg and vast parts of the surrounding lands belonged to the Archbishops of Mainz. Time and again, the Hessians and Mainzers came to blows over who had ascendancy over these lands. As of the 13th century, the landgraves of Hesse further upgraded Kirchhain as a Hessian bulwark against Mainz's centre of Amöneburg so that they could control the region. Kirchhain then developed into the economic centre of the Amöneburg Basin. Kirchhain was presumably given town rights before 1348, but without any earlier documentary proof, the year 1352 has come to be seen as the official year of the town's founding. From the 15th century, the important Lange Hessen and Cologne-Leipzig trade roads made of Kirchhain a road hub and thereby spurred on the town's further economic development. Its good traffic connections, however, led to Kirchhain's being occupied a few times during the Thirty Years' War, becoming for a time the headquarters of various armies, and thereby having to suffer as troops were billeted in the town. In 1636, about 12,000 to 14,000 soldiers were being housed in and around the town. For the 1,000 or
