Which Central American country experienced a successful leftist revolution?

In the context of Central America, the country that experienced a leftist revolution is Nicaragua.1

In 1979, the Sandinista National Liberation Front (FSLN) successfully led an insurrection that toppled the long-standing dictatorship of the Somoza family, which had dominated the country since 1936. Following their victory, the Sandinistas established a socialist-oriented government that initiated various land, economic, and educational reforms aimed at addressing poverty and inequality.123

However, the revolution faced significant challenges, including a civil war against U.S.-backed insurgents known as the Contras and severe economic decline. The Sandinista government eventually lost power in the 1990 presidential elections to the National Opposition Union. The FSLN later returned to power in 2007 under the leadership of Daniel Ortega, though the subsequent administration adopted a different economic approach and became increasingly authoritarian.132
