Málaga's history spans about 2,800 years, making it one of the oldest cities in the world. According to most scholars, it was founded about 770 BC by the Phoenicians as Malaka From the 6th century BC the city was under the hegemony of Ancient Carthage, and from 218 BC, it was ruled by the Roman Republic and then empire as Malaca (Latin). After the fall of the empire and the end of Visigothic rule, it was under Islamic rule as Mālaqah for 800 years, but in 1487, the Crown of Castille gained control after the Reconquista. The archaeological remains and monuments from the Phoenician, Roman, Arabic and Christian eras make the historic center of the city an "open museum", displaying its history of nearly 3,000 years.

This important cultural infrastructure and the artistic heritage have culminated in the nomination of Málaga as a candidate for the 2016 European Capital of Culture.

The painter and sculptor Pablo Picasso, Hebrew poet and Jewish philosopher Solomon Ibn Gabirol and the actor Antonio Banderas were born in Málaga. The magnum opus of Cuban composer Ernesto Lecuona, "Malagueña", is named after the music of this region of Spain.

Seville is the capital and largest city of the autonomous community of Andalusia and the province of Seville, Spain. It is situated on the plain of the river Guadalquivir. The inhabitants of the city are known as sevillanos (feminine form: sevillanas) or hispalenses, after the Roman name of the city, Hispalis. Seville has a municipal population of about 690,000 as of 2016, and a metropolitan population of about 1.5 million, making it the fourth-largest city in Spain and the 30th most populous municipality in the European Union. Its Old Town, with an area of 4 square kilometres (2 sq mi), contains three UNESCO World Heritage Sites: the Alcázar palace complex, the Cathedral and the General Archive of the Indies. The Seville harbour, located about 80 kilometres (50 miles) from the Atlantic Ocean, is the only river port in Spain. Seville is also the hottest major metropolitan area in the geographical Southwestern Europe, with summer average high temperatures of above 35 °C (95 °F).

Seville was founded as the Roman city of Hispalis. It later became known as Ishbiliyya after the Muslim conquest in 712. During the Muslim rule in Spain, Seville came under the jurisdiction of the Caliphate of Córdoba before becoming the independent Taifa of Seville; later it was ruled by the Muslim Almoravids and the Almohads until finally being incorporated into the Christian Kingdom of Castile under Ferdinand III in 1248. 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 (House of Trade) 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 Guadalquivirforced 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.
