Kornburg was first mentioned in a document in 1236 as the seat of the Imperial Minister Konrad von Kornburg (also: Chunradus de Chvrenburc). The name is probably derived from the Kornberg. The ridge extends north of Kornburg, from Wendelstein to Worzeldorf. Good millstones for water mills were already being broken in its quarries in Carolingian times. The Middle High German name for the millstone and the mill was Kurn, Kürn or Kürne.[4]
The burgrave Friedrich II bestowed the butigler (imperial estate administrator/cuper) Konrad von Kornburg for his services as a hereditary fief Kornburg, the forest, the mountain (Kornberg with the valuable quartzite sandstone quarries) and everything that went with it.
The Nuremberg burgraves from the Hohenzollern family, who held the office of judge in Kornburg from 1342 to 1717, granted the Reichsdorf market rights in 1364. Initially, a makeshift fortification surrounded the market. The castle was built in 1288 (or earlier). In the 14th century, Kornburg was briefly owned by the Küdorfer family, a patrician family with ministerial positions. Through marriage, Kornburg fell to von Hohenfels (from Freystadt near Allersberg/Hohenfels) in 1405 and to Hans von Seckendorff in 1422. His son, Jörg von Seckendorff, sold the manor, castle and fortress in 1447 to his brother-in-law Peter Rieter. During the War of the Cities and the Margrave Wars, Kornburg was severely damaged in parts, almost completely destroyed by Wallenstein's troops in the Thirty Years' War and the population wiped out except for a few survivors.
Around 1790 there were 51 margravial and 23 Nuremberg estates in Kornburg, which naturally led to ongoing tensions in the past. After the transition to Prussia in 1792 (JKA Schwabach), Kornburg fell to Bavaria in 1806 (LG Schwabach). In 1808 the tax district was formed, and in 1818 the market town of Kornburg.
