Otranto - Santa Maria di Leuca e Bosco di Tricase" wanted by the Apulia Region in 2008. This territory has numerous natural and historical attractions such as Ciolo, which is a rocky cove. History Apulia is one of the richest archaeological regions in Italy. It was first colonized by Mycenaean Greeks. The Greeks referred to the region as Iapygía (whence 'Apulia') owing to the presence of the three main Iapygian tribes that inhabited Apulia during the first millennium B.C. – the Daunians in the North, the Peucetians in the Centre, and the Messapians in the South. Some parts of the regions were conquered by the Muslim Saracens and the Emirate of Bari was established for a brief period of time by Muhammad Abul Abbas of Sicily. A number of castles were built in the area by the King of Sicily and Holy Roman Emperor Frederick II, including Castel del Monte, sometimes called the "Crown of Apulia". Apulia was an autonomous duchy until 1130 when its duke became king of Sicily. After 1282, when the kingdom lost the island of Sicily itself, Apulia remained part of the remnant Kingdom of Naples (confusingly known also as the Kingdom of Sicily), and remained so until the unification of Italy in 1861. This kingdom was independent under the House of Anjou from 1282 to 1442, then was part of Aragon until 1458, after which it was again independent under a cadet branch of the House of Trastámara until 1501. As a result of the French–Spanish war of 1501–1504, Naples again came under the rule of Aragon and the Spanish Empire from 1504 to 1714. When Barbary pirates of North Africa sacked Vieste in 1554, they took an estimated 7,000 slaves. The coast of Apulia was occupied at times by the Turks and at other times by the Venetians. In 1861 the region became part of the Kingdom of Italy. Economy The region's contribution to Italy's gross value added was around 4.6% in 2000, while its population was 7% of the total. The per capita GDP is low compared to the national average and represents about 68.1% of the EU average. The share of gross value added by the agricultural and services sectors was above the national average in 2000. The region has industries specialising in particular areas, including food processing and vehicles in Foggia; footwear and textiles in the Barletta province, and wood and
