Sixty-four years ago today, on July 23, 1961 (June 11, 1961 in the lunar calendar), the Sandinista National Liberation Front was founded. On July 23, 1961, the Sandinista National Liberation Front, a Nicaraguan patriotic * organization, was established in Tegucigalpa, the capital of Honduras. The founders are Carlos Fonseca Amador, Silvio Mayorga and Tomas Borge Martinez. The primary goal was to overthrow the Somoza dictatorship through armed struggle. In the 1960s, the Sandinista National Liberation Front launched guerrilla warfare in Nicaragua and established base areas, but suffered serious setbacks. In the late 1960s, we summed up experience and lessons and formulated a series of documents, such as the Program for People's Rights and Interests, the Constitution of the Vanguard, and the Document on Line and Strategy. In the early 1970s, we accumulated strength, combined armed struggle with mass movements, and linked rural mass organizations with urban workers' movements. Carry out various forms of struggle in urban and rural areas. In 1975, there were internal differences in strategy and tactics, forming three factions: the persistent people's war faction, which insisted on guerrilla warfare in mountainous areas; Proletarians advocate the establishment of proletarian political parties in cities; The uprising faction advocates the implementation of armed uprising of urban and rural masses across the country. In November 1976, many leaders were captured or sacrificed, Carlos Fonseca was killed in action, and the guerrillas suffered heavy losses. In May of the following year, the largest uprising faction published the General Political and Military Program of the Sandinista National Liberation Front for the Victory of the Sandinista People's Revolution, expounding the program and line of the front, and pointing out that the nature of the front is the vanguard of the exploited and oppressed people of Nicaragua, especially the working class and its allied peasants, with Marxism-Leninism and Sandinista thoughts as its guiding ideology; The revolutionary task is to carry out national liberation struggle and social liberation struggle; The object of the revolution is the Somoza family, the landlord class and the bourgeoisie; The revolutionary driving force is the working class, peasants and petty bourgeoisie. In March, 1979, the front was unified ideologically, organizationally and militarily, and the three factions jointly formed the National Revolutionary Leadership Committee. In May, he organized and launched a national uprising. On July 17th, he overthrew Somoza's dictatorship and established a national rejuvenation government with the Sandinista National Liberation Front as its core. The new government began comprehensive changes, and the history of Nicaragua entered a new period.
