During the Bulgarian National Revival Sliven was an important commercial craft center and cultural education center. The first textile factory in Bulgaria was built here, namely the First Textile Factor of Dobri Zhelyazkov-Fabrikadzhiyata, thus marking the beginning of the industrial development on the Bulgarian land. The traditions in the production of textiles and knitwear have been preserved until today.
