Santa Fe, Argentina in the context of Brigadier Estanislao López Highway

Asunción (English: /ɑːˌsuːnsiˈoʊn, ˌɑːsuːnˈsjoʊn/, Spanish: [asunˈsjon]; Guarani: "Paraguay") is the capital and the largest city of Paraguay. The city stands on the eastern bank of the Paraguay River, almost at the confluence of this river with the Pilcomayo River. The Paraguay River and the Bay of Asunción in the northwest separate the city from the Occidental Region of Paraguay and from Argentina in the south part of the city. The rest of the city is surrounded by the Central Department.

Asunción is one of the oldest cities in South America and the longest continually inhabited area in the Río de la Plata Basin; for this reason it is known as "the Mother of Cities". From Asunción, Spanish colonial expeditions departed to found other cities, including the second foundation of Buenos Aires, that of other important cities such as Villarrica, Corrientes, Santa Fe, Córdoba, Santa Cruz de la Sierra and 65 more. According to the 2022 Paraguayan Census, Asunción has 462,241 inhabitants, while its metropolitan area (known as Greater Asunción) exceeds 2.3 million inhabitants, making it the most densely populated area in Paraguay, and also the most productive as it concentrates 70% of the National GDP. Asunción is the third most populated "jurisdiction" or "political division" in the country, surpassed by the Central and Alto Paraná departments.

Entre Ríos (Spanish pronunciation: [ˈentɾe ˈri.os], 'Between Rivers') is a central province of Argentina, located in the Mesopotamia region. It borders the provinces of Buenos Aires (south), Corrientes (north) and Santa Fe (west), and Uruguay in the east.

Its capital is Paraná (391,000 inhabitants), which lies on the Paraná River, opposite the city of Santa Fe.

The Constitution of the Argentine Nation (Spanish: Constitución de la Nación Argentina) is the basic governing document of Argentina, and the primary source of existing law in Argentina. Its first version was written in 1853 by a constitutional assembly which gathered in Santa Fe; the doctrinal basis was taken in part from the United States Constitution. It was then reformed in 1860, 1866, 1898, 1949, 1957 (which mainly repealed the 1949 reform), and the current version is the reformed text of 1994. It's the seventh oldest national constitution currently in effect being ratified on May 1, 1853.

The Argentine Constitution consists of a preamble and two normative parts:

Santa Fe, officially Province of Santa Fe (Spanish: Provincia de Santa Fe, Spanish pronunciation: [ˈsanta ˈfe], lit. "Holy Faith") is a province of Argentina, located in the center-east of the country. Neighboring provinces are from the north clockwise Chaco (divided by the 28th parallel south), Corrientes, Entre Ríos, Buenos Aires, Córdoba, and Santiago del Estero. Together with Córdoba and Entre Ríos, the province is part of the economico-political association known as the Center Region.

Santa Fe's most important cities are Rosario (population 1,193,605), the capital Santa Fe (369,000), Rafaela (100,000), Reconquista (99,000) Villa Gobernador Gálvez (74,000), Venado Tuerto (69,000), and Santo Tomé (58,000).

Candombe is a style of music and dance that originated in Uruguay among the descendants of liberated African slaves. In 2009, the United Nations Educational, Scientific and Cultural Organization (UNESCO) inscribed candombe in its Representative List of the Intangible Cultural Heritage of Humanity.

To a lesser extent, candombe is practiced in Argentina, Paraguay, and Brazil. In Argentina, it can be found in Buenos Aires, Santa Fe, Paraná, and Corrientes. In Paraguay, this tradition continues in Camba Cuá and in Fernando de la Mora near Asunción. In Brazil, candombe retains its religious character and can be found in the states of Minas Gerais and Rio Grande do Sul.

The current Constitution of the Argentine Republic dates back from 1853. The Argentine Constitution of 1853 was approved in 1853 by almost all of the provincial governments with the exception of Buenos Aires Province, which remained separate from the Argentine Confederation until 1859. After several modifications to the original constitution and the return of power to Buenos Aires' Unitarian Party, it was sanctioned on May 1, 1853, by the Constitutional Convention that had gathered in Santa Fe. The document was promulgated by the provisional director of the national executive government, Justo José de Urquiza, who was a member of the Federalist Party. Following the short-lived constitutions of 1819 and 1826, it was the third constitution in the history of the country.

Despite several reforms of varying importance, the 1853 constitution formed the basis of the current Argentine juridical system. It was closely inspired by the juridical and political doctrines of the United States Constitution. It established, for example, a Republican division of powers, a high level of independence for provinces, and a federal power controlled by a strong executive government that was limited by a bicameral national congress to balance the population's representation. It also drew from the previous constitutions, as well as the pioneering works of the jurist Juan Bautista Alberdi.

The Toba people, also known as the Qom people, are one of the largest Indigenous groups in Argentina who historically inhabited the region known today as the Pampas of the Central Chaco. During the 16th century, the Qom inhabited a large part of what is today northern Argentina, in the current provinces of Salta, Chaco, Santiago del Estero, Formosa and the province of Gran Chaco in the southeast of the Department of Tarija in Bolivia (which the Qom have inhabited since the 20th century). Currently, many Toba, due to persecution in their rural ancestral regions, live in the suburbs of San Ramón de la Nueva Orán, Salta, Tartagal, Resistencia, Charata, Formosa, Rosario and Santa Fe and in Greater Buenos Aires. Nearly 130,000 people currently identify themselves as Toba or Qom. With more than 120,000 Qom living in Argentina, the Qom community is one of the largest Indigenous communities in the country.

Like most Indigenous groups in South America, the Qom have a long history of conflict and struggle following the arrival of the Spanish. While the Qom incorporated some aspects of European society into their culture, such as horseback riding, violent conflicts were fairly common. The Toba people, in particular, opposed the ideas of Christianity and the systems of forced labor that were imposed upon the Qom during the lives at Jesuit reductions. In some cases, attempts to assimilate the Toba people to Spanish society were accomplished with force and, when met with resistance from the Indigenous group, resulted in massacres such as the Massacre of Napalpí. In more recent history, the Qom have struggled with problems such as poverty, malnutrition, discrimination and tuberculosis due to a lack of support from the community and the inequalities they have endured.
