From Wikipedia, the free encyclopedia: Portugal, officially the Portuguese Republic is a country on the Iberian Peninsula, in Southwestern Europe. It is the westernmost country of mainland Europe. To the west and south it is bordered by the Atlantic Ocean and to the east and north by Spain. The Portugal–Spain border is 1,214 kilometres (754 miles) long and considered the longest uninterrupted border within the European Union. The republic also includes the Atlantic archipelagos of the Azores and Madeira, both autonomous regions with their own regional governments. The territory of modern Portugal has been continuously settled, invaded and fought over since prehistoric times. The Pre-Celts, Celts, Phoenicians, Carthaginians and the Romans were followed by the invasions of the Visigothic and the Suebi Germanic peoples. In 711 the Iberian Peninsula was invaded by the Moors and for the following centuries Portugal would be part of Muslim Al Andalus. Portugal was born as a result of the Christian Reconquista, and in 1139, Afonso Henriques was proclaimed King of Portugal, thus firmly establishing Portuguese independence.
