Lisbon
Lisbon is one of the oldest cities in the world, and one of the oldest in Western Europe, predating other modern European capitals such as London, Paris, and Rome by centuries. Julius Caesar made it a municipium called "Felicitas Julia", adding to the name "Olissipo". Ruled by a series of Germanic tribes from the 5th century, it was captured by the Moors in the 8th century. In 1147, the Crusaders under Afonso Henriques reconquered the city and since then it has been a major political, economic and cultural centre of Portugal. Unlike most capital cities, Lisbon's status as the capital of Portugal has never been granted or confirmed officially – by statute or in written form. Its position as the capital has formed through constitutional convention, making its position as "de facto" capital a part of the Constitution of Portugal.
History of Lisbon
In 711, Islamic Moors, who were mostly Berbers and Arabs from the Maghreb, invaded the Christian Iberian Peninsula, conquering Lisbon in 714. What is now Portugal first became part of the Emirate of Córdoba and then of its successor state, the Caliphate of Córdoba. Despite attempts to seize it by the Normans in 844 and by Alfonso VI in 1093, Lisbon remained a Muslim possession. In 1147, after a four-month siege, Christian crusaders under the command of Afonso I captured the city and Christian rule returned. In 1256, Afonso III moved his capital from Coimbra to Lisbon, taking advantage of the city’s excellent port and its strategic central position.
