Där jämför de Spaniens och Storbritanniens synvinkel på tvisten.
Spaniens:Anglo-Dutch forces captured the fortress of Gibraltar in 1704, during the War of the Spanish Succession. It was formally ceded to the British in perpetuity under Article X of the Treaty of Utrecht in 1713. The Gibraltar territory was designated a Crown Colony in 1830 and was listed as such by the UN in 1946. In 1964, the Gibraltar Constitution was introduced and promulgated in 1969, stipulating that sovereign status would not be changed without the consent of Gibraltar's people.
Spanien erkänner att Gibraltar var under brittisk överhöghet mellan 1713 och 1880. Vad hände 1880 som ändrade det hela??From AD711 to 1462 Gibraltar was under Moorish rule, like most of Spain. Spain (initially Castile) controlled the territory from 1462 to 1704. Its political status between 1704 and 1713 was that of a territory occupied by allied Anglo-Dutch forces during the War of the Spanish Succession. Gibraltar's sovereign status between 1713 and 1880 was that of a territory taken by right of conquest, but legitimised in the form of a cession to the British (Article X, Treaty of Utrecht, 1713, Appendix I).
1880 nämns inte i den brittiska synvinkeln och en snabbsök på nätet gav inget svar heller.
