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.”

Throughout their history, the countries of Central America have attempted several forms of political and economic integration. After declaring independence in the 19th century, the region lacked its earlier cohesion vis-à-vis Spanish colonial governance. The former provinces aligned themselves in favor of either centralizing regional power in a federal republic or establishing complete political autonomy through the formation of new nation-states. Forces in favor of the latter eventually prevailed.
An attempt at economic integration began in the mid-20th century. It was actively backed by the United Nations Economic Commission for Latin America and the Caribbean (ECLAC) and eventually led to the creation of the Central American Common Market (CACM). Despite favorable economic conditions in the Post-World War II period, a number of complications undermined integration efforts: war, political crises, and interests that ran contrary to those of the United States. Integration was postponed until the end of the 1980s, after the Esquipulas II Accord reestablished peace in the region.
After the countries of Central America signed the Guatemala Protocol in 1993, economic integration was promoted under the banner of free trade. This was done by regional economic groups with the goal of reconnecting the region to global commerce under the most advantageous circumstances possible.

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.

The Transatlantic Financial Crisis of 1837 produced a global depression that lasted until the mid-1840s. Falling cotton prices, a collapsing land bubble, and fiscal and monetary policies pursued by individual actors and financial institutions in the United States and Great Britain were all responsible. A comprehensive understanding of the panic must take into account the global movements of gold and silver that linked Mexico, China, the United States, and Great Britain in complex networks of credit and debt. In the United States, businesses, banks, and individuals declared bankruptcy; states defaulted on their debts; commodity prices dropped; credit instruments lost their value; and unemployment rose amid a general atmosphere of pessimism and an erosion of confidence. The severity of the panic prompted politicians and financial theorists to reevaluate their ideological assumptions regarding the proper role of governmental regulation in an economy. In a larger sense, the panic demonstrated how the expansion of slavery in the United States, British imperialism, financial speculation, and recurring cycles of boom and bust were emerging as defining features of modern capitalism.
