Zadar, Italian Zara, Latin Jadera, picturesque historical town in southwestern Croatia, the former capital of Dalmatia. It is located on the end of a low-lying peninsula that is separated by the Zadar Channel from the islands of Ugljan and Pašman. The inlet between the peninsula and the mainland creates a natural deepwater harbour.
The old town on the peninsula dates from the 9th century BCE, when it was a Liburnian settlement called Jadera. The town became Roman in the 1st century BCE. Spared in the Avar and Slavic invasions of Dalmatia (c. 5th–6th century CE), it remained a thriving commercial, cultural, and artistic centre of Byzantine Dalmatia. Between 1045 and 1358 the town was intermittently at war with Venice, and in 1409 it was sold to Venice. From this point the town was oppressed by the Venetians from within and the Turks from without. It withstood a Turkish attack in 1571, and in the succeeding period Zadar became the most heavily fortified town on the Adriatic until its fortifications were partly demolished in the late 19th century.
The town was an Austrian possession from 1797 to 1920, except for a brief French interregnum between 1808 and 1813. By the Treaty of Rapallo (1920), Zadar became Italian, thereby losing further ground to Split as the chief town of Dalmatia. During the course of World War II, Allied bombing destroyed 75 percent of Zadar’s buildings and damaged the port facilities. Liberated in 1944, it became part of Yugoslavia.
