According to the first tradition, the name Barcelona is a shortened form of Barke-no, the original name given to the city by Iberian immigrants. According to the second tale, Barcelona was named by the Carthaginians, and the name derives from the Carthaginian surname Barca, which means "ray." The modern Catalan word for barcelona is barcàdnava, with the definite article el. Thus, "the Barcelona" is referred to as el barcàdnava. During the Spanish Civil War (1936-39), Barcelona was known as la capital hispano-fria because Madrid had been taken by Franco's forces. In January 1939, King Alfonso XIII returned to Spain after being forced to abdicate in France, and Barcelona again became the capital of Catalonia. After the war, Barcelona's economy grew rapidly, leading to the construction of many skyscrapers. The port also expanded, with large numbers of tourists arriving each year. Thus, Barcelona became one of Europe's most prosperous cities. However, the growth of tourism has caused problems with overcrowding and traffic congestion. Barcelona is now considered to be a world class city, with a powerful economy based on trade, finance, marketing, design, and technology. It is also known for its culture, cuisine, and architecture.
