Plaza de la República (Republic Square) is a city square in Buenos Aires, capital of Argentina. It is located in the San Nicolás quarter, at the intersection of the city's three main arteries: Ninth of July Avenue, Corrientes Avenue, and Diagonal Norte. It derives its name and associations from a church once sited on the square, San Nicolás de Bari (demolished in the 1930s for the creation of 9 July Avenue), where the country's national flag was hoisted for the first time. The plaza is the site of the Obelisk of Buenos Aires, designed by Alberto Prebisch and inaugurated in 1937. The plaza, originally a circular esplanade paved in stone, was enlarged to its current dimensions in 1962. Its present layout was established in 1971, when Corrientes Avenue was rerouted through the plaza and around the obelisk to ease car traffic into the city's financial district.

Buenos Aires ( or ; Spanish pronunciation: [ˈbwenos ˈajɾes] (listen)), officially the Autonomous City of Buenos Aires (Spanish: Ciudad Autónoma de Buenos Aires), is the capital and largest city of Argentina. The city is located on the western shore of the Río de la Plata, on South America'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, Italy. 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. Its citizens first elected a Chief of Government in 1996; previously, the Mayor was directly appointed by the President of Argentina. The Greater Buenos Aires conurbation, which also includes several Buenos Aires Province districts, constitutes the fourth-most populous metropolitan area in the Americas, with a population of around 15.6 million. It is also the second largest city south of the Tropic of Capricorn. 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.It is known for its preserved eclectic European architecture and rich cultural life. It is a multicultural city that is home to multiple ethnic and religious groups, 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. Buenos Aires held the 1st FIBA World Championship in 1950 and 11th FIBA World Championship in 1990, the 1st Pan American Games in 1951, was the site of two venues in the 1978 FIFA World Cup and one in the 1982 FIVB Men's World Championship. Most recently, Buenos Aires had a venue in the 2001 FIFA World Youth Championship and in the 2002 FIVB Volleyball Men's World Championship, hosted the 125th IOC Session in 2013, the 2018 Summer Youth Olympics and the 2018 G20 summit.

The French blockade of the Río de la Plata was a two-year-long naval blockade imposed by France on the Argentine Confederation ruled by Juan Manuel de Rosas. It closed Buenos Aires to naval commerce. It was imposed in 1838 to support the Peru–Bolivian Confederation in the War of the Confederation, but continued after the end of the war. France did not land ground forces, but instead took advantage of the Uruguayan Civil War and the Argentine Civil Wars, supporting Fructuoso Rivera and Juan Lavalle against Manuel Oribe and Rosas. After two years without the expected results, France signed the Mackau-Arana treaty with the Argentine Confederation, ending the hostilities.
