Prehistory
The district of present day Zadar has been populated since prehistoric times. The earliest evidence of human life comes from the Late Stone Age, while numerous settlements have been dated as early as the Neolithic. Before the Illyrians, the area was inhabited by an ancient Mediterranean people of a pre-Indo-European culture. They assimilated with the Indo-Europeans who settled between the 4th and 2nd millennium BC into a new ethnical unity, that of the Liburnians. Zadar was a Liburnian settlement, laid out in the 9th century BC, built on a small stone islet and embankments where the old city stands and tied to the mainland by the overflown narrow isthmus, which created a natural port in its northern strait.
Antiquity
The Liburnians were known as great sailors and merchants, but also had a reputation for piracy in the later years. By the 7th century BC, Zadar had become an important centre for their trading activities with the Phoenicians, Etruscans, Ancient Greeks and other Mediterranean peoples. Its population at that time is estimated at 2,000. From 9th to 6th century there was certain koine - cultural unity in the Adriatic Sea, with the general Liburninan seal, whose naval supremacy meant both political and economical authority through several centuries. Due to its geographical position, Zadar developed into a main seat of the Liburnian thalassocracy and took a leading role in the Liburnian tetradekapolis, an organization of 14 communes.
The people of Zadar, the Iadasinoi, were first mentioned in 384 BC as the allies of the natives of Hvar and the leaders of an eastern Adriatic coast coalition in the fight against the Greek colonizers. An expedition of 10,000 men in 300 ships sailed out from Zadar and laid siege to the Greek colony Pharos in the island of Hvar, but the Syracusan fleet of Dionysus was alerted and attacked the siege fleet. The naval victory went to the Greeks which allowed them relatively safer further
