was a lack of internal coherence in political ideas (this can be seen in the publication of the newspaper Trinchera). The first few years were carried by some basic shared values of all the forces that were being integrated. Some of these basic shared ideas was to imitate the success of the Cuban Revolution, the ineffectiveness of the conventional opposition to the Somoza regime and the need to remain independent of them (referring to the from the conservative, liberal and communist parties), the need for a revolutionary movement that would use the armed struggle as opposition to the Somoza dictatorship, and after some discussion, identification with Sandino's struggle. It was not until 1969 that any programmatic document was published. The Sandinista National Liberation Front was supposedly founded in a meeting in Tegucigalpa (Honduras) between Carlos Fonseca, Tomás Borge, and Silvio Mayorga. It's even been said that the meeting was held on July 19, 1961. In reality, there is no documentary reference that supports this affirmation, with the first news of this meeting and date surfacing after the revolutionary triumph of 1979. The term "Sandinista" was adopted two years later, establishing continuity with Sandino's movement, and using his legacy to develop the newer movement's ideology and strategy. By the early 1970s, the FSLN was launching limited military initiatives. Rise (1970–1976) On December 23, 1972, a magnitude 6.2 earthquake leveled the capital city, Managua. The earthquake killed 10,000 of the city's 400,000 residents and left another 50,000 homeless. About 80% of Managua's commercial buildings were destroyed. President Anastasio Somoza Debayle's National Guard embezzled much of the international aid that flowed into the country to assist in reconstruction, and several parts of downtown Managua were never rebuilt. The president gave reconstruction contracts preferentially to family and friends, thereby profiting from the quake and increasing his control of the city's economy. By some estimates, his personal wealth rose to US$400 million in 1974. In December 1974, a guerrilla group affiliated with FSLN directed by Eduardo Contreras and Germán Pomares seized government hostages at a party in the house of the Minister of Agriculture in the Managua suburb Los Robles, among them several leading Nicaraguan officials and Somoza relatives. The siege was carefully timed to take place after the departure of the US ambassador from the gathering. At 10:50 pm, a group of 15 young guerrillas and their commanders, Pomares and Contreras, entered the house.
