Peru after i960 experienced significant changes in its social structure, a notable expansion and intensification of political participation and advances in the national integration of the peasants. Six candidates contested the presidential elections of 1962. The most important were Haya de la Torre, in his first presidential bid since 1931, the former dictator general Manuel Odria and Fernando Belaunde Terry. The Revolutionary Government of the Armed Forces decreed a series of changes of a clearly authoritarian, nationalist, anti-oligarchic nature, which shook the foundations of society. The 'second phase' of the military revolution began with the transfer of state control to the military junta, composed of the chiefs of the armed forces. Interest in the 1985 elections was focussed on two political fronts, Izquierda Unida (IU) and Alianza Popular Revolucionaria Americana (APRA), and two new figures who had redefined the representation of the political interests of the country's middle and lower classes: Alfonso Barrantes of IU and Alan Garcia of APRA.
