While Europeans basked in the glory of their so-called century of peace between the end of the Napoleonic wars (1815) and the onset of World War I (1914), Latin Americans knew no such luxury. Conflict became a way of life for Latin Americans attempting to construct nation-states. Liberals and Conservatives dueled with one another for political power, while caudillos (military strongmen) added their unique twisted logic to the political process. Historians have spilled considerable ink detailing these internal conflicts that complicated Latin America’s struggle for effective state formation in the early national period but have paid much less attention to the external wars over disputed boundaries that involved every South American nation during the 19th century. As historian Robert Burr described it: boundary conflicts were the “congenital international disease of Spain’s former colonies.”
In 1863 and 1864, historical and political contradictions in the River Plate region led to civil war in Uruguay, creating tensions with neighboring nations in the region. The Brazilian government intervened both politically and militarily in Uruguay to address the interests of ranchers in its province of Rio Grande do Sul, to distract the attention of the Brazilian citizens from domestic problems, and to preserve the political influence of the Empire of Brazil on Uruguay. This action by the Empire clashed with the new Paraguayan policy of political interference in the River Plate region and resulted in the declaration of war against Brazil by Paraguayan dictator Francisco Solano López. This conflict broadened into the Paraguayan War.

Since the implementation of the Brazilian Republic in 1889, its history has been shaped by the political role of the armed forces, particularly the army. From 1964 to 1985, the Brazilian military was in direct command of the state, appointing generals as presidents through indirect elections. After overthrowing the center-left reformist government of João Goulart, on March 31, 1964, the military imposed an authoritarian regime of tutelage of the political party system and of civil society, which served as a political model for similar regimes in Latin America during the Cold War.
The military imposed arbitrary laws and cracked down on leftist political groups and social movements. They sought to boost capitalist development and “national integration” within the vast area of Brazilian territory, modernizing industry and updating the nation’s infrastructure. However, the military encountered strong opposition from civil society, which was led by political groups and the press, as well as intellectuals and artists from different ideological backgrounds (Marxists, liberals, socialists, and progressive Catholics). These groups were divided over whether to refuse to negotiate with the military or to take a critical stance in relation to the policies of the military governments, resulting in complex social relationships.
Social actors and contemporary politicians continue to vie for ownership of society’s memories of the period, making it necessary to combine historical research with historiographical criticism for understanding the role of the military regime in the nation’s history.
Between 1472 and 1572, the conquests of Peru were many: by the Inca, who in the 15th century spread from their southern Andean heartland in Cusco to build an empire that stretched from what is now southern Colombia to northern Chile and Argentina; by the Spanish conquistadors under the leadership of Francisco Pizarro and Diego de Almagro, who reached down from Panama in search of the rumored wealth of the kingdom of “Birú” and fatefully encountered the aspirant Inca emperor Atahualpa at Cajamarca in November of 1532; by the Spanish crown, which intervened after the revolt of Atahualpa’s brother Manco Inca in 1536 and the rebellion of the conquistadors in the 1540s; and by the Inca’s former subjects, the Spaniards’ Indian allies, and their mestizo sons, who ended independent Inca resistance by helping to capture Atahualpa’s nephew in the Vilcabamba valley in 1572. This essay sketches the century-long arc of those many conquests, which together yielded a historical entity not quite like any other in the early modern world, let alone Americas: a composite Spanish-Indian kingdom whose incredible wealth lay not just in the gold and silver that its mines and burials produced but in the network of subjects and laborers that drew both the Inca and their Habsburg successors on to further conquests than was wise.
Since 1982 there have been at least 2,000 massacres in Colombia committed by different illegal groups and by members of the Colombian army and police. The development of the conflict in Colombia has a direct relation with the causes and consequences of these crimes, perpetrated in most cases by paramilitary armies, associated to varying degrees with the cocaine trade. Paramilitary groups were a counterinsurgency force organized by the State, or independent, and supported economically by drug cartels and some landowners and businessmen.
Although guerrilla armies, insurgency, and communist groups created mostly in the 1960s perpetrated several massacres, these crimes were systematically used primarily by paramilitary groups to terrorize people in places where they had a particular interest, such as drug trafficking or vying for political power. In its book ¡Basta ya!, the Centro Nacional de Memoria Histórica has documented that 59% of the massacres were committed by paramilitary groups and 17% by guerrillas.
Rutas del Conflicto is a project created by journalists that marks the evolution of these groups through more than 30 years of war. Using mapping and timeline tools developed especially for the project, it has documented more than 700 of these crimes, displaying the degree to which the tragedy has affected the lives of millions of people in Colombia.

The English-speaking world awaits its first detailed study examining Latin America during World War I. Many historical events of the era remain little-known, as does much of the region’s military history during this period. While key chronologies, personalities, groups, and historical avenues remain unidentified, researchers must draw knowledge from existing texts. The authors cited in this article for further study cover only a small fraction of the myriad topics presented by the war.
World War I set in motion a unique power readjustment in Latin America, the likes of which had not been experienced in the region since the 1820s. Most significantly, the temporary suspension of economic ties with Europe disrupted everyday processes that elites and commoners had previously taken for granted. Changes in economy and finance triggered a struggle between indigenous Americans, peasants, workers, elites, and immigrants, setting the stage for the social and political changes of the 1920s. Amidst the upheaval of World War I, non-elite Latin American groups successfully focused national politics on regional and ethnic issues, while elite Latin Americans weighed the potential advantages of ties with Spanish and Italian authoritarianism. World War I ended European financial dominance over the region, and the destruction of Europe reduced export markets to a point where Latin America’s economic relations with the United States gained new significance. U.S. military advisors took their places alongside European trainers, and many different “U.S.” actors emerged on Latin American soil, acting out rivaling understandings of appropriate U.S. activity in Latin America. The war heralded the end of Belgian influence and of significant French power in the region, British acceptance of U.S. financial preeminence, and questions as to how Prussian military expertise could be leveraged to Latin America’s benefit in the future. The creation of the League of Nations, a development alien to Latin American political culture, caught the region off guard. And yet it laid the foundation for global Latin American diplomacy in the 1930s and after World War II. In the end, the search for a new understanding of a Latin American nation’s place on the changing world stage led to the elevation of the institution of the national army as a social and political arbiter. The myth of the army as embodiment of national essence would last until the 1980s.

The Mexican-American War ranks among the most consequential events in the history of both nations. Although the casus belli for the United States’s May 12, 1846, declaration of war was the Mexican ambush of a U.S. Army patrol in the disputed Nueces Strip on April 25 of that year, two underlying causes rendered conflict inevitable. The dispute over Texas was the first, and the desire of both nations to control the Mexican provinces of Nuevo Mexico and California was the second. President James Knox Polk identified the acquisition of that territory as the principal objective of his administration.
The conflict also remains noteworthy for the extent to which the political milieu in both countries proved as important as events on the battlefields. In México, a devastating war of independence (1810–1821), multiple violent overthrows of the federal government, the failure of two constitutions to produce a structure acceptable to both conservatives and liberals, and enmities generated by the socioeconomic structure severely limited México’s growth, tranquility, and potential for armed resistance to an invader. In the United States, the national unity evident at the outbreak of the war faded in the face of sectional rivalries, unexpectedly high casualties, and declining relations between the executive and legislative branches.
The military phases of the war fall into two segments. In the first, forces considerably smaller than those deployed in later phases of the war fought in Texas and in the Mexican provinces of Nuevo Mexico, California, Tamaulipas, and Nuevo Leon. When United States victories in northern Mexico failed to produce the anticipated Mexican surrender, the second phase of the conflict began on March 9, 1847, with General Winfield Scott’s invasion of central Mexico and ended with his entrance in Mexico City on September 14, 1847.
In the following seven months, both governments sought to obtain the best terms. A rising tide of violent rural rebellion in Mexico and a rising tide of Whig opposition to the Polk administration in Washington served as catalysts during the negotiations. Two agreements, the February 2, 1848, Treaty of Guadalupe-Hidalgo and the March 6, 1848, Truce Agreement brought hostilities a close.
Consequences of the conflict included the Mexico’s loss of 525,000 square miles of territory, the emergence of the United States as the dominant continental power, the dispossession of many Mexican citizens living in what had become U.S. territory, and the reestablishment of Mexican sovereignty over territories in rebellion.

In the period 1870–1936, Paraguay began to redevelop economically after its devastating loss in the War of the Triple Alliance (1864–1870). Turning to a liberal economic model popular in the region at the time, government officials began selling off large tracts of land to foreign investors, in particular Argentine investors. The liberal era in Paraguay was notoriously turbulent as political rivals often relied on Civil War to gain power. Nonetheless, this period was pivotal in helping to shape ideas about the nation. The era ends at the Febrerista Revolution (1936) when returning Chaco War (1932–1935) veterans made their mark on Paraguayan politics and identity.

The effort of searching the effects of the War of the Triple Alliance against Paraguay on the building up of Brazilian national identity challenges the historian with a paradox: why the military victory promotes the fall of the political regime instead of strengthening it. The article tries to deal with some dimensions of this paradox underlining the distinctive characteristics of this war in the ongoing warmongering in the Platine region—the huge numbers of conscripted soldiers (“the Total War”), the hybrid political character of the alliance (Brazilian monarchy and Argentinian Republic), the opposition of most of the conservative classes, and the unveiling of slavery as a strategic weakness for the country—are some of the themes treated in order to explain how the empire lost both the battle of worldwide moral support and the battle of legitimacy inside the country. The massive recruitment coming from all parts of the country could bring the empowerment of ordinary people in the postwar decades, but the monarchical elites took careful steps to ensure that these sectors were quickly demobilized and also not to receive medals and other military honors. The postwar era was one of unfolding of an endemic crisis leading to contest of monarchical institutions. They came from military sectors, but also from regional elites, besides bitter criticism from middle-class intellectuals. Racial arguments filled an outstanding part in this period, leading to the giving prestige of “scientific” racism and the negative diagnosis for the future of a modern nation founded in a racially mixed society.
In the late 1960s, several leftist political movements in Latin America began to claim the use of political violence as a means of social transformation. This second wave of leftist political violence was distinct from an earlier wave—composed of rural guerillas inspired by the Cuban Revolution, roughly a decade and a half earlier—in several ways. The later proponents of armed struggle emphasized the importance of cities in armed actions, not just rural settings. They also advocated interaction between armed organizations and other actors in social movements, including far-left nationalist and populist factions within traditional political parties and the Catholic Church. Armed action was seen by such groups as a valid response to increasingly repressive governments, and to limitations on political action that made social change through peaceful means impossible. The use of violence provided a way to develop collective action in the hostile environment of the Latin American Cold War, which was marked by extreme political and ideological polarization.
