Departments of Paraguay in the context of Boquerón, Paraguay

Chaco (Spanish pronunciation: [ˈtʃako]; Wichi: To-kós-wet), officially the Province of Chaco (Spanish: provincia del Chaco [pɾoˈβinsja ðel ˈtʃako]) is one of the 23 provinces of Argentina. Its capital and largest city is Resistencia. It is located in the north-east of the country.

It is bordered by Salta and Santiago del Estero to the west, Formosa to the north, Corrientes to the east, and Santa Fe to the south. It also has an international border with the Paraguayan department of Ñeembucú. With an area of 99,633 km (38,469 sq mi) and a population of 1,142,963 as of 2022, it is the twelfth most extensive, and the eleventh most populated, of Argentina's provinces.

Central (Spanish pronunciation: [senˈtɾal]) is a department in Paraguay. Its capital is situated in Areguá. With more than 1.8 million inhabitants, it is the most populated of the 17 departments of Paraguay. It is also the smallest department, with a total area of 2,465 square kilometres (952 mi).

Alto Paraná (Spanish pronunciation: [ˈalto paɾaˈna]; Upper Paraná) is a department in Paraguay. The capital is Ciudad del Este (formerly known as Puerto Presidente Stroessner, originally Puerto Flor de Lis).

The Alto Paraná department has experienced tremendous economic and population growth in the past 50 years. Most of this growth has been concentrated in the department capital of Ciudad del Este, and mainly occurred after the construction of the Puente de la Amistad bridge in 1961, which connects Paraguay and Brazil. This department is home to the Itaipu power plant, which supplies 95% of the energy consumed by Paraguay, and the Acaray Dam. Several ecological reserves, a zoo and the Taiwanese-Paraguayan Technology Park are situated in this department.

The National Republican Association (Spanish: Asociación Nacional Republicana, ANR), also known as the Colorado Party (Spanish: Partido Colorado, lit. 'Red Party'), is a conservative political party in Paraguay, founded on 11 September 1887 by Bernardino Caballero. Since 1947, the colorados, as they are known, has been dominant in Paraguayan politics (ruling as the only legal party between 1947 and 1962) and has controlled the presidency since 1948 – notwithstanding a brief interruption between 2008 and 2013 – as well as having a majority in both chambers of Congress and department governorships, it was one of the two traditionally dominant parties in the country, along with the Authentic Radical Liberal Party (PLRA).

The Colorado Party has historically been and continues to be the dominant political party in Paraguay. With 2.6 million members as of 2022 (although there are allegations of numerous false affiliations made by the party), it is the largest political party in the country, usually ruling without the necessity of electoral alliances. Paraguay was for several decades under dictatorial rule by Alfredo Stroessner, a member of the Colorado Party, until he was ousted from power in 1989, which set off a democratization process. Since then, there has been an expansion of civil and political liberties, as well as elections at presidential, congressional, and municipal levels. However, the democratization process has been limited due to the firm control of the Colorado Party on the Paraguayan state. The Colorado Party retains power through clientelistic practices, and corruption is widespread in Paraguay.
