Buenos Aires vs Tucson

Informations

Buenos Aires ( or ; Spanish pronunciation: [ˈbwenos ˈajɾes]), officially Autonomous City of Buenos Aires, is the capital and largest city of Argentina. The city is located on the western shore of the estuary of the Río de la Plata, on the South American continent's southeastern coast. "Buenos Aires" can be translated as "fair winds" or "good airs", but the former was the meaning intended by the founders in the 16th century, by the use of the original name "Real de Nuestra Señora Santa María del Buen Ayre", named after the Madonna of Bonaria in Sardinia. The Greater Buenos Aires conurbation, which also includes several Buenos Aires Province districts, constitutes the fifth-most populous metropolitan area in the Americas, with a population of around 15.6 million.The city of Buenos Aires is neither part of Buenos Aires Province nor the Province's capital; rather, it is an autonomous district. In 1880, after decades of political infighting, Buenos Aires was federalized and removed from Buenos Aires Province. The city limits were enlarged to include the towns of Belgrano and Flores; both are now neighborhoods of the city. The 1994 constitutional amendment granted the city autonomy, hence its formal name of Autonomous City of Buenos Aires (Ciudad Autónoma de Buenos Aires; "CABA").

Its citizens first elected a chief of government (i.e. mayor) in 1996; previously, the mayor was directly appointed by the President of the Republic. Buenos Aires' quality of life was ranked 91st in the world in 2018, being one of the best in Latin America. In 2012, it was the most visited city in South America, and the second-most visited city of Latin America (behind Mexico City).It is known for its preserved eclectic European architecture and rich cultural life. Buenos Aires held the 1st Pan American Games in 1951 and was the site of two venues in the 1978 FIFA World Cup. Most recently, Buenos Aires hosted the 2018 Summer Youth Olympics and the 2018 G20 summit.Buenos Aires is a multicultural city that is home to multiple ethnic and religious groups. Several languages are spoken in the city in addition to Spanish, contributing to its culture as well as to the dialect spoken in the city and in some other parts of the country. This is because since the 19th century, the city, and the country in general, has been a major recipient of millions of immigrants from all over the world, making it a melting pot where several ethnic groups live together. Thus, Buenos Aires is considered one of the most diverse cities of the Americas.

Tucson was founded as a military fort by the Spanish when Hugo O'Conor authorized the construction of Presidio San Agustín del Tucsón in 1775. It was included in the state of Sonora after Mexico gained independence from the Spanish Empire in 1821. In 1853, the United States acquired a 29,670 square miles (76,840 km2) region of present-day southern Arizona and southwestern New Mexico from Mexico under the Gadsden Purchase. Tucson served as the capital of the Arizona Territory from 1867 to 1877. Tucson was Arizona's largest city by population during the territorial period and early statehood, until it was surpassed by Phoenix by 1920. Nevertheless, population growth remained strong during the late 20th century. In 2017, Tucson was the first American city to be designated a "City of Gastronomy" by UNESCO.The Spanish name of the city, Tucsón [tukˈson], is derived from the O'odham Cuk Ṣon [tʃʊk ʂɔːn], meaning "(at the) base of the black [hill]", a reference to a basalt-covered hill now known as Sentinel Peak. Tucson is sometimes referred to as "The Old Pueblo".
