The subsequent historical references speak of a long period in which the island was completely abandoned, to then become a land of conquest for the Phoenicians, Carthaginians, Romans and Visigoths.
Despite the many dominations, it is only starting from the XNUMXth century, with the Arab conquest of Spain, that Formentera also experienced a period of economic and social development. In fact, some of the most important finds belong to the Conquest: wells, buildings, cisterns, patios ...
In 1235 Formentera was conquered by Guillermo de Montgrí on behalf of the king of Aragon Jaime I, and included in the Kingdom of Mallorca. Jaime I and his troops liberated the island from the last Muslim populations, with the intention of repopulating it with inhabitants of Aragonese Spain, but the attempt failed, both for the inhospitable conditions of the island and for the attacks of the Berbers, and in the XNUMXth century the island is again abandoned.
Throughout the Middle Ages and the Renaissance Formentera will be inhabited only occasionally by people from Ibiza, and it will only be in 1695 that the island - sold by the Crown to Ibiza for "the services rendered" - will be permanently inhabited.
After the construction of the Church of Sant Francesc and its urban nucleus, small towns were created on the island, and gradually Formentera had almost 2000 inhabitants (in the eighteenth century, against the first 400).
It was only from the 60s and 70s of the last century that Formentera, like the rest of the Balearics, experienced true economic development, based on service and tourist offer, characterized on this island by a relaxing and peaceful atmosphere. , in stark contrast to that of Ibiza. From the economic development comes the island's desire to separate from Ibiza, and to have its own Consell Insular: but the result is late in coming, and Formentera only becomes independent in 2007, after the reform of the Statute of the Balearics in 1983.
Currently the Consell Insular de Formentera is working on the connections (almost non-existent outside the tourist period) between the island, the rest of the Balearics and Spain.
