Answer:
In the 1980s, Nicaragua experienced a pro-Communist revolution led by the Sandinistas.
Step-by-step explanation:
The Nicaraguan Revolution was a process that began in 1978 in Nicaragua, led by the Sandinista Front for National Liberation. This event marked the end of the dictatorship of the Somoza family in Nicaragua. The FSLN took power on July 19, 1979. The ideological background of this process was socialism, with a strong influence of Marxism. The revolution was not only important for Nicaragua and Central America but was marked as one of the most tense moments in the Cold War.
A year later, a new war between the Contras and the Sandinistas began, which lasted until the 1990s. The Contras received financial and military support from the US government from an early stage, as President Ronald Reagan supported them. After the U.S. Congress banned support for the Contras, the Reagan administration secretly sent them money from the profits they made after selling weapons to Iran. These secret activities became known as the Iran-Contra Affair. In 1988, negotiations began between the warring parties, culminating in the February 1990 elections. That year, when the FSLN lost the election, is considered the end of the Sandinista revolution.
