According to historians, the beginnings of Jablunkov are to be found in the place where the present-day village of Hradek is located. It was first mentioned in a written document in 1435. In 1447 Magyars completely destroyed the settlement. In 1560 Wacław III, Duke of Cieszyn, granted town rights to the town. It continuously developed and by the end of the 16th century it had a mayor and a city council. The town profited from its location in the Jablunkov Pass. It was located on an ancient trade route going from the Mediterranean Sea to the Baltic Sea. The route was used by merchants of ancient Rome; frequent discoveries of Roman coins confirm that. Important trading routes to Krakow (north) and to Upper Hungary (east) also run through the town. It became more and more important and also rich, as many citizens lived by trading. In the middle of the 17th century, it had, together with a suburb and a village of Pioseczna, 750 inhabitants. In the 18th century most of citizens worked in trade, craftsmanship and farming. At the end of the 19th century, many new buildings were built. A new Art Nouveau town hall was built in 1905. After the division of Cieszyn Silesia in 1920 it became a part of Czechoslovakia. In October 1938 it was annexed by Poland together with whole region known as Zaolzie, and during World War II was a part of Nazi Germany. After the war it once again became part of Czechoslovakia
