Pre-Roman coins found in the area of Barcelona suggest that the Celtic-Iberian Laietani tribe may have settled here. Around 230 BC the Carthaginian conqueror Hamiclar Barca, father of Hannibal, established a settlement here giving the city own name. Archaeologists believe that this town has been built on the hill of Montjuic. The Romans arrived in Spain in 218 BC. The heart of the Roman settlement lies within the Barri Gothic. Remains of city walls, temple pillars and graves all attest to what would become eventually a busy and lovely town. Barcino, as the Romans called it, was not a major center. Tarraco (modern Tarragona) was considerably more important. From the 4th century AD onwards several waves of invaders flooded across the country. The Visigoths arrived in 415 and made a temporary capital in Barcelona. In 711 Muslims landed in Hispania. They made their way through the country into France, where only brought to a halt in 732 by the Franks at Poitiers. Barcelona was taken by the Frankish rule Louis the Pious in 801.
The real history of Barcelona begins at this point. The area was populated by the people who by then could be identified as 'Catalans". Their language was closely related to the lange d’oc, the language of southern France. By the late 10th century the Casa de Barcelona ruled an independent principality covering most of modern Catalunya. This was the only Christian state on the Iberian Peninsula. In the 11th century Catalunya launched its own fleet and the sea trade developed. This was the era of great Catalan Romanesque art. Barcelona’s trading wealth paid for the great Gothic buildings. The cathedral, the Capella Real de Santa Agata and the churches of Santa Maria del Pi and Santa Maria del Mar were built in the late 13th or early 14th century.
A 1462 rebellion against King Joan II ended in a siege in 1473 that devastated the city. The sea wars with Genoa, resistance in Sardinia and the loss of the gold trade all drained the coffers and eventually Catalunya became part of the Castilian state. The Catholic Monarchs banned Catalans from trading directly with newly established American colonies. Disaffected Catalans resorted to arms a number of times, and the last revolt, during the War of the Spanish Succession, saw Catalonia siding with Britain and Austria against Felipe V, the French contender for the Spanish throne. Barcelona fell in 1714 after another shocking siege, and as well as banning the Catalan language, Felipe built a huge fort, the Ciutadella, to watch over his ungrateful subjects.
The big break came only in 1778 when the ban on American trade was lifted, and the region's fortunes gradually turned around. Spain's first industrial revolution, based on cotton, was launched there, and other industries based on wine, cork, and iron also developed. By the 1830s, the European Romantic movement virtually rescued Catalan culture and language.
