Portugal, officially the Portuguese Republic (Portuguese: República Portuguesa [ʁɛˈpuβlikɐ puɾtuˈɣezɐ]), is a country whose mainland is located on the Iberian Peninsula of Southwestern Europe, and whose territory also includes the Atlantic archipelagos of the Azores and Madeira. It features the westernmost point in continental Europe, and its Iberian portion is bordered to the west and south by the Atlantic Ocean and to the north and east by Spain, the sole country to have a land border with Portugal. Its two archipelagos form two autonomous regions with their own regional governments. Lisbon is the capital and largest city by population. Portugal is the oldest continuously existing nation state on the Iberian Peninsula and one of the oldest in Europe, its territory having been continuously settled, invaded and fought over since prehistoric times. It was inhabited by pre-Celtic and Celtic peoples who had contact with Phoenicians and Ancient Greek traders, it was ruled by the Romans, followed by the invasions of the Suebi and Visigothic Germanic peoples, in turn followed by the Moors who eventually were expelled. Portugal as a county was established during the early Christian Reconquista. Founded in 868, the County of Portugal gained prominence after the Battle of São Mamede (1128). The Kingdom of Portugal was later proclaimed following the Battle of Ourique (1139), and independence from León was recognized by the Treaty of Zamora (1143). (Source: Wikipedia.org, CC BY-SA)
