History of Plovdiv tradition. The name "Plovdiv" first appeared around that time and is derived from the city's Thracian name "Pulpudeva" (assumed to be a translation of Philippopolis, from Pulpu = Philippou and deva = city), which was rendered by the Slavs first as "Pəldin" ("Пълдин") or "Pləvdin". Under the rule of the Ottoman Empire, Plovdiv was a focal point for the Bulgarian national movement. During that period Plovdiv was an economic center along with Constantinople, Odrin and Thessaloniki. Due to trade, the emerging Bulgarian bourgeoisie became significant in the society. Trading with Russia and Europe these people experienced political and cultural influences.
