Kiskőrös has been populated since the late Iron Age. In the first century Transdanubia was invaded by the Romans and its population ran away and settled in the area. In the 1930s five Avar villages and seven cemeteries have been discovered. The first written documents mentioning Kiskõrös date back to 1398. By 1433 Kõrös was an independent town. The peaceful life of the town came to an end in the 16th century when the Turkish army occupied the region. A letter was written on April 11, 1529 by Mihály Pósa warning the bishop of Kalocsa about the attacks of the Turks. The town lost much of its population during the occupation. The rebirth of Kiskõrös is the work of the Wattay family. For their contribution to defeat the Turks, Leopold I gave the family the land and the surrounding areas. On May 19, 1718 700 Slovakian farmers moved to Kiskõrös. The population has reached 5,000 by 1785. On January 1, 1823 Sándor Petőfi was born in Kiskõrös. In the 20th century Hungary lost both world wars and during the years of the Great Depression the economy of the village suffered greatly. Kiskõrös was occupied by the Soviet Army in 1944. After WWII, most of the income came from agriculture (wine and fruit production). Kiskőrös began to develop rapidly in the 1970s and infrastructure, educational, healthcare and welfare institutions were built. Kiskõrös became a town again in 1973
