How did Latin American countries return to civilian democracy in the late 20th century?

In the late 20th century, the transition from military rule to civilian democracy across Latin America was driven by a combination of domestic pressure, economic instability, and, in specific instances, external intervention.1

Military regimes, often characterized as bureaucratic authoritarianism, frequently stepped down because national militaries preferred to return to their barracks rather than risk internal divisions or the loss of public legitimacy. As these regimes encountered economic crises—often exacerbated by the debt crisis of the 1980s—their ability to maintain control weakened.213

The process of democratization varied by country:
* Domestic Pressure: In many nations, the force of public opinion, combined with foreign disapproval and internal squabbling among military officers, compelled a transition to elective civilian government.1
* External Factors: In Argentina, the military government’s defeat in the Falkland Islands War discredited the regime and forced a return to democracy. In other cases, such as Panama in 1989 and Haiti in 1994, U.S. intervention played a direct role in removing military or dictatorial leadership.1

By the end of the century, regular electoral procedures had become the standard for changing governments, marking a significant shift from the military coups of previous decades.1
