The first inhabitants of the island of Brač were ancient Illyrians whose presence dates back to the early history. Numerous fortresses and ruins scattered along the island prove their presence on the island of Brač but also their strength to resist a strong Greek colonization of mid-Dalmatian islands in 4th Century B.C. Roman period from 167 BC has conditioned that life moved to the northern coasts and bays of Brač, but there were built no settlements but villae rusticae on the cape of St Nicholas in Supetar in Lovrečina bay, in locality Mirje near Postire and other. Under Roman rule on the island, Brač was also the economic centre.
