Ibiza (city)

[edit] The first inhabitants of the area were Phoenicians and Aiboshim is claimed to have been founded in 654 BC. The city had a population of 3,000 to 4,000 by the 5th century BC. The city was incorporated into the Roman Republic as a federated city until Emperor Vespasian turned it into Municipius Flavius Ebusus in 70 AD. The area was conquered by the Vandals in 424, and by the Byzantine Empire in 535. The area was incorporated into Al-Andalus in the 10th century and a new irrigation system was developed during this period. During the reign of King James I of Aragon the island was conquered by Guillem de Montgrí in August 1235. King James II of Aragon established a local government in 1299, and this lasted until 1717. The city was attacked by Peter of Castile during a war between Castile and Aragon in 1354. King Philip V of Spain issued the Decree of New Planta in 1715, which introduced the town hall government. The town was granted the title of city by King Charles III of Spain in 1782. The title of city was required for the creation of the Roman Catholic Diocese of Ibiza in 1782; Manuel Abad y Lasierra was its first bishop. UNESCO declared the city a World Heritage Site on 4 December 1999.
