Gibraltar, at the south end of the Iberian Peninsula, is a rocky promontory commanding the western entrance to the Mediterranean. Aside from its strategic importance, it is also a free port, naval base, and coaling station. It was captured by the Moorish leader Tarik, crossing from Africa into Spain in 711, and its name is derived from the Arabic, Jabal-al-Tarik (Mount of Tarik). In the 15th century, it passed to the Moorish ruler of Granada and later became Spanish. It was captured by an Anglo-Dutch force in 1704 during the War of the Spanish Succession and passed to Great Britain by the Treaty of Utrecht in 1713. Since then Spain has continually laid claim to it. Most of the inhabitants of Gibraltar are of Spanish, Italian, and Maltese descent, and in 1981 Gibraltarians were granted full British citizenship. Spanish efforts to recover Gibraltar culminated in a referendum in 1967, in which the residents voted overwhelmingly to retain their link with Britain. In response, Spain sealed Gibraltar's land border between 1969 and 1985.
In 2002, Britain and Spain discussed sharing the sovereignty of Gibraltar. In reaction, the government of Gibraltar held a referendum in Nov. 2002 in which the population voted almost unanimously against shared sovereignty.
