Plovdiv has evidence of habitation since the 6th millennium BC. By the end of the 4th millennium BC there already was an established Neolithic settlement there. In the 12th century BC the village evolved into a real town populated by Thracians ranking it among world's oldest cities. It was possibly invaded by Persians, later by Greeks, Celts, Romans, Goths, Huns, Bulgarians, Slav-Vikings, Crusaders and Turks. On 4 January 1878, Plovdiv was liberated from Ottoman rule by the Russian army. It remained within the borders of Bulgaria until July of the same year, when it became the capital of the autonomous Ottoman region of Eastern Rumelia. In 1885, Plovdiv and Eastern Rumelia joined Bulgaria.
