Carlos Salinas de Gortari in the context of Raúl Salinas de Gortari

The North American Free Trade Agreement (Spanish: Tratado de Libre Comercio de América del Norte, TLCAN; French: Accord de libre-échange nord-américain, ALÉNA), referred to colloquially in the Anglosphere as NAFTA, (/ˈnæftə/ NAF-tə) was an agreement signed by Canada, Mexico, and the United States that created a trilateral trade bloc in North America. The agreement came into force on January 1, 1994, and superseded the 1988 Canada–United States Free Trade Agreement between the United States and Canada. The NAFTA trade bloc formed one of the largest trade blocs in the world by gross domestic product.

The impetus for a North American free trade zone began with U.S. president Ronald Reagan, who made the idea part of his 1980 presidential campaign. After the signing of the Canada–United States Free Trade Agreement in 1988, the administrations of U.S. president George H. W. Bush, Mexican president Carlos Salinas de Gortari, and Canadian prime minister Brian Mulroney agreed to negotiate what became NAFTA. Each submitted the agreement for ratification in their respective capitals in December 1992, but NAFTA faced significant opposition in both the United States and Canada. All three countries ratified NAFTA in 1993 after the addition of two side agreements, the North American Agreement on Labor Cooperation (NAALC) and the North American Agreement on Environmental Cooperation (NAAEC).

Since declaring independence in 1821, Mexico has adopted a number of constitutions or other documents of basic law with constitutional effects. Not all these can be considered constitutions, and not all of them enjoyed universal application. Those enacted in 1824, 1857, and 1917 are generally considered full-fledged, operational constitutions. The Constitution of 1824 established the framework of a federated republic, following the short-lived monarchy of Agustín de Iturbide (in 1821–22). The Constitution of 1857 was the framework set by Mexican liberals that incorporated particular laws into the constitution. The Constitution of 1917 was drafted by the faction that won the Mexican Revolution, known as the Constitutionalists for their adherence to the Constitution of 1857. It strengthened the anticlerical framework of the 1857 constitution, empowered the state to expropriate private property, and set protections for organized labor. The 1917 Constitution was significantly revised in 1992 under Carlos Salinas de Gortari, eliminating anticlerical restrictions and strengthening private property rights against the State.

An ejido (Spanish pronunciation: [eˈxiðo], from Latin exitum) is an area of communal land used for agriculture in which community members have usufruct rights rather than ownership rights to land, which in Mexico is held by the Mexican state. People awarded ejidos in the modern era farm them individually in parcels and collectively maintain communal holdings with government oversight. Although the system of ejidos was based on an understanding of the preconquest Aztec calpulli and the medieval Spanish ejido, since the 20th century ejidos have been managed and controlled by the government.

After the Mexican Revolution, ejidos were created by the Mexican state to grant lands to peasant communities as a means to stem social unrest. As Mexico prepared to enter the North American Free Trade Agreement in 1991, President Carlos Salinas de Gortari declared the end of awarding ejidos and allowed existing ejidos to be rented or sold, ending land reform in Mexico.

General elections were held in Mexico on 6 July 1988. They were the first competitive presidential elections in Mexico since the Institutional Revolutionary Party (PRI) took power in 1929. The elections were widely considered to have been fraudulent, with the PRI resorting to electoral tampering to remain in power.

PRI candidate Carlos Salinas de Gortari was proclaimed the winner of the presidential election, with the Ministry of Interior reporting he received 51% of the vote. It was the lowest for a winning candidate since direct presidential elections were inaugurated in 1917; in all previous presidential elections, the PRI faced no serious opposition and won with well over 70% of the vote. In the Chamber of Deputies election, the PRI won 260 of the 500 seats, as well as winning 60 of the 64 seats in the Senate election.

Ernesto Zedillo Ponce de León (Spanish pronunciation: [eɾˈnesto seˈðiʝo]; born 27 December 1951) is a Mexican economist and politician. He was the 61st president of Mexico from 1994 to 2000, as the last of the uninterrupted 71-year line of Mexican presidents from the Institutional Revolutionary Party (PRI). Father of Modern Democracy in Mexico, his non-interventionist policy yielded transparent results on the 2000 Mexican general election.

During his presidency, he faced one of the worst economic crises in Mexico's history, which started only weeks after taking office. While he distanced himself from his predecessor Carlos Salinas de Gortari, blaming his administration for the crisis, and overseeing the arrest of Salinas' brother Raúl Salinas de Gortari, he continued the neoliberal policies of his two predecessors. His administration was also marked by renewed clashes with the EZLN and the Popular Revolutionary Army; the controversial implementation of Fobaproa to rescue the national banking system; a political reform that allowed residents of the Federal District (Mexico City) to elect their own mayor; the privatization of national railways and its subsequent suspension of the passenger rail service; and the Aguas Blancas and Acteal massacres perpetrated by State forces.
