Paraguay

Long before European contact, the lands between the Paraguay and Paraná rivers were inhabited by Guaraní-speaking peoples, who practiced shifting cultivation of cassava and maize and lived in extended kin groups led by hereditary chiefs. To their west, in the harsher Chaco, lived semi-nomadic groups including the Guaycurú, Ayoreo, and various Lengua-Maskoy communities. These societies maintained extensive trading and warring contacts across the river basin, and Guaraní cosmology, language, and place names left a lasting imprint that survives in Paraguay's bilingual culture today.

Spanish navigators reached the region in the 1520s, and in 1537 Juan de Salazar founded the fort of Asunción, which became the chief Spanish base for the wider Río de la Plata. Throughout the colonial period, Asunción served as a launching point for expeditions further south and east, but the territory itself remained relatively isolated and economically marginal. From the early seventeenth century, Jesuit missionaries organised much of the Guaraní population into the famous reducciones, semi-autonomous mission villages that flourished as centres of agriculture, crafts, and Guaraní-language literacy until the Society of Jesus was expelled from Spanish America in 1767. Colonial Paraguay was administered first from Lima and then, after 1776, from the Viceroyalty of the Río de la Plata centred on Buenos Aires.

Paraguay declared independence from Spain in May 1811, avoiding incorporation into the new Argentine state. The early republic was shaped by three long rulers: José Gaspar Rodríguez de Francia, who governed as supreme dictator from 1814 until 1840 and pursued strict isolation, and the López family, Carlos Antonio (1844 to 1862) and his son Francisco Solano (1862 to 1870), who modernised the army, built railways, and cultivated foreign expertise. Paraguay's trajectory was shattered by the War of the Triple Alliance (1864 to 1870) against Brazil, Argentina, and Uruguay, a catastrophic conflict that killed a large share of the male population, reduced the territory, and left the country impoverished for generations.

The decades that followed saw chronic instability under the rival Colorado and Liberal parties, periodic coups, and the costly Chaco War with Bolivia (1932 to 1935), which Paraguay won at heavy cost while securing most of the disputed Chaco Boreal. Politics grew steadily more militarised, culminating in the 1947 civil war and the rise of General Alfredo Stroessner, who seized power in 1954 and ruled for thirty-five years through the Colorado Party, internal repression, and selective economic development, including the binational Itaipú hydroelectric project with Brazil.

Stroessner was overthrown in February 1989 by General Andrés Rodríguez, who oversaw a transition to electoral democracy and the promulgation of a new constitution in 1992. The Colorado Party retained the presidency through the 1990s and 2000s despite repeated crises, including the 1999 assassination of Vice President Luis María Argaña and an ensuing political upheaval. Fernando Lugo's election in 2008 briefly broke six decades of Colorado rule before his removal by congressional impeachment in 2012; the Colorados returned under Horacio Cartes, then Mario Abdo Benítez, and most recently Santiago Peña, elected in 2023.

Paraguay today is a presidential, unitary republic with a directly elected head of state and a bicameral Congress, operating under the 1992 constitution that frames the institutions described in the remainder of this dossier.
