After the discovery of the Americas , Seville became one of the economic centres of the Spanish Empire as its port monopolised the trans-oceanic trade and the Casa de Contratación -LRB- House of Trade -RRB- wielded its power , opening a Golden Age of arts and literature . In 1519 , Ferdinand Magellan departed from Seville for the first circumnavigation of the Earth . Coinciding with the Baroque period of European history , the 17th century in Seville represented the most brilliant flowering of the city 's culture ; then began a gradual economic and demographic decline as silting in the Guadalquivir forced the trade monopoly to relocate to the nearby port of Cádiz .   The 20th century in Seville saw the tribulations of the Spanish Civil War , decisive cultural milestones such as the Ibero-American Exposition of 1929 and Expo ' 92 , and the city 's election as the capital of the Autonomous Community of Andalusia .
