Even as trusted friends of the family succeeded Luis in the presidency, his brother remained firmly in control of the National Guard. Eventually, in 1967, Anastasio himself was elected president; Luis soon died of a heart attack, leaving Anastasio in sole control. Without his brother's technocratic influence, Anastasio's corrupt ways were unrestrained. The 1972 Nicaragua earthquake, which severely damaged the capital of Managua, brought further evidence of corruption, as members of the National Guard openly looted damaged businesses and misappropriated international aid, and Somoza Debayle's personal wealth soared during the reconstruction period. In 1974, the growing Sandinista movement FSLN (named after the assassinated Sandino) succeeded in forcing the government to accept an amnesty, after which Somoza Debayle declared a state of siege and the National Guard launched a violent and repressive reaction in the period 1975–76. Though the FSLN was weakened, so was the regime.
