can be traced to Indo-Iranians origins. Their former designation of Ász changed unter Turkish and Slavic influences to Jász. Their settlements ranged from the southern borders of the Mátra westward to the Gödöllő Hills (Hungarian Gödöllői-dombság), eastwards almost to the river Tisza and south to the modern-day Szolnok. South of them, the Kipchaks (Hungarian Kun) were settled. In the 15th century, these two regions formed a castle-district with the center at Berény, which also became county-capital of the Jász-Nagykun-Szolnok County until 1876. 1536, the Jászság was attacked and conquered by Turkish forces. They established a military post at Jászberény in the remains of the former Franciscan abbey and the 1472 erected church. After the end of the Turkish rule, Leopold I sold the Jászság to the Teutonic Knights (22. March 1702) and disestablished the privileges of the county. The Teutonic Knights also took Jászberény as main seat and made it the official capital of the county Jászkun, consisting out of Jászság, Kiskunság and Nagykunság. In the general population, the sale was opposed. The region therefore supported Francis II Rákóczi in Rákóczi's War of Independence but, after defeat, they took to legal means, collected the required sum and bought their own county back. 1745, the re-buy (redemption) was approved by Maria Theresa of Austria who also reestablished the county's privileges. As a consequence of the Hungarian Revolution of 1848, the autonomous administration of the Jászkun region were abolished again. The three-part region was divided up and parts were assigned to two new counties with the capitals of Jászberény and Jászápati. 1860, the region regained its self-administration for the last time only to ultimately lose it 1877. Kiskunság was divided between the Pest and the Bács comitat. Jászság and Nagykunság formed the new comitat of Jász-Nagykun-Szolnok. The new capital of the comitat became Szolnok and Jászberény lost its former importance. In the 1950s, various industrial firms chose to settle in Jászberény which had been very much an agricultural community up to this point. This development resulted in an increase in the number and type of jobs available and brought increased prosperity to the inhabitants of Jászberény. Despite the economic difficulties of recent years, Jászberény has continued to grow and has been able to invest in the necessary infrastructure. At the same time, more and more firms have chosen Jászberény as a centre for their operations. However, Jászberény not only values economic growth
