The area underwent rapid industrialization (coal, steel, zinc) in the 19th and the beginning of 20th century. However, it remained a cluster of industrial settlements and villages until the 1950s, when it was administratively united. It never developed into a truly unified city.
After the fall of communism in 1989, the significant heavy industry was largely scaled down or restructured. The area has been transforming to a service-based economy. The well-known still operating coal mine is "Halemba".
