the pioneering teachings and method of Paulo Freire. The government also proposed to hold a university reform and prohibited the operation of private schools. Fifteen percent of Brazil's income would be directed to education. Tax reform to control the transfer of profits by multinational companies with headquarters abroad, instead reinvesting profits in Brazil. The income tax would be proportional to personal profit. Electoral reform to extend voting rights to illiterate people and low-ranking military officers. Land reform to expropriate and redistribute non-productive properties larger than 600 hectares to the population. At that time, the agricultural population was larger than the urban population. Cuba, 1962 With the Cuban Missile Crisis, Kennedy sent a letter to Goulart proposing the participation of the Brazilian military in the possible invasion of the island. In response, Goulart demonstrated that he opposed this plan and instead supported the self-determination of the peoples. In a reply he stated that "we will never recognize war as an instrument capable of resolving conflicts between nations" and sent a letter to Fidel Castro with the same concerns as the US government, but standing against the invasion. With this position, Kennedy began to develop a personal hostility against Goulart and began to believe that the Brazilian president was a threat to the security of the United States. The military coup In the early hours of 31 March 1964, General Olímpio Mourão Filho, in charge of the 4th Military Region, headquartered in Juiz de Fora, Minas Gerais, ordered his troops to start moving toward Rio de Janeiro to depose Goulart. On 1 April, at 12:45 p.m., João Goulart left Rio for the capital, Brasília, in an attempt to stop the coup politically. When he reached Brasília, Goulart realized that he lacked any political support. The Senate president, Auro de Moura Andrade, was already calling for congressional support of the coup. Goulart stayed for a short time in Brasília, gathering his wife and two children, and flying to Porto Alegre in an Air Force Avro 748 aircraft. Soon after Goulart's plane took off, Auro de Moura Andrade declared the position of President of Brazil "vacant". In the first hours of 2 April, Auro de Moura Andrade, along with the president of the Supreme Federal Court, swore in Pascoal Ranieri Mazzilli, the speaker of the house, as president. This move was arguably unconstitutional at the time, as João Goulart was still in the country.
