BUZULUK Komárov, a. s., formerly Železárny v Komárově, is one of the oldest companies in the Czech Republic. Its origins date back to the 15th century. In 1543, Jan the Younger, Pešík of Komárov, had his property “with Baštiny, smelters, mountains and mines” registered again after the fire of the land records. In 1602 Jindřich Otta of Los bought the Komárov estate including the smelters. In 1623 Marie Eusebie, Countess of Martinice, acquired the smelter by purchase and merged it with the Horovice estate.
In the second half of the 17th century (from 1690), the ironworks belonged to the count family from Vrbno , in 1852 they became the property of Elector Bedřich Wilhelm I of Hesse and until 1902 they belonged to the estate of the Hanavian princely family.
In 1902, the ironworks were purchased by C. T. Petzold and Co. and in 1919 it changed into a joint-stock company with its registered office in Prague. In 1948 the company was nationalised and since 1949, when it was renamed BUZULUK Komárov n.p., it has undergone a number of different organisational changes. Since 6 May 1992, the state enterprise BUZULUK Komárov has become a joint-stock company.
