Barcelona

According to tradition, Barcelona was founded by either the Phoenicians or the Carthaginians, who had trading posts along the Catalonian coast. In the Middle Ages, Barcelona became the capital of the County of Barcelona. After joining with the Kingdom of Aragon to form the composite monarchy of the Crown of Aragon, Barcelona, which continued to be the capital of the Principality of Catalonia, became the most important city in the Crown of Aragon and its main economic and administrative centre, only to be overtaken by Valencia, wrested from Moorish control by the Catalans, shortly before the dynastic union between the Crown of Castile and the Crown of Aragon in 1516. Barcelona became the centre of Catalan separatism, briefly becoming part of France during the 17th century Reapers' War and again from 1812 to 1814 under Napoleon.
