President Tiburcio Carías—founder of the National Party of Honduras—governed Honduras throughout the 1930s and 1940s (known as “decades of Dictators” in Central America as El Salvador, Nicaragua, and Guatemala were also under lasting rule of their respective, oppressive dictators). His presidency started on February 1, 1933, and lasted until January 1949. On November 16, 1943, Carías and the National Party rigged and swept the municipal elections. This victory gave him the opportunity to modify the Honduran Constitution to allow him to stay in office for an extended period of time.
In 1936, Anastasio Somoza was elected president of Nicaragua. He ran under the the Liberal Nationalist Party, or PLN. He was elected with broad support among liberals in Nicaragua, although, soon after his election, small numbers of Nicaraguans started to gather in opposition to his presidency. In 1937, a small group of university graduates formed a dicussion group that was highly critical of Somoza; the members of this unnamed group would go on to found the Independent Liberal Party, or PLI - the organization that led the campaign against Somoza in 1944.
In 1938, El Salvadoran president General Maximiliano Hernández Martínez proposed changing the country’s constitution so that he could continue holding his position beyond the end of his second term.
