arms under Rafael Caldera's first presidency (1969–1974); Caldera had won the 1968 election for COPEI, being the first time a party other than Democratic Action took the presidency through a democratic election. The new democratic order had its antagonists. Betancourt suffered an attack planned by the Dominican dictator Rafael Trujillo in 1960, and the leftists excluded from the Pact initiated an armed insurgency by organizing themselves in the Armed Forces of National Liberation, sponsored by the Communist Party and Fidel Castro. In 1962 they tried to destabilize the military corps, with failed revolts in Carúpano and Puerto Cabello. At the same time, Betancourt promoted a foreign policy, the Betancourt Doctrine, in which he only recognized elected governments by popular vote. The election in 1973 of Carlos Andrés Pérez coincided with an oil crisis, in which Venezuela's income exploded as oil prices soared; oil industries were nationalized in 1976. This led to massive increases in public spending, but also increases in external debts, which continued into the 1980s when the collapse of oil prices during the 1980s crippled the Venezuelan economy. As the government started to devalue the currency in February 1983 to face its financial obligations, Venezuelans' real standards of living fell dramatically. A number of failed economic policies and increasing corruption in government led to rising poverty and crime, worsening social indicators, and increased political instability. In the 1980s, the Presidential Commission for State Reform (COPRE) emerged as a mechanism of political innovation. Venezuela was preparing for the decentralization of its political system and the diversification of its economy, reducing the large size of the State. The COPRE operated as an innovation mechanism, also by incorporating issues into the political agenda that were generally excluded from public deliberation by the main actors of the Venezuelan democratic system. The most discussed topics were incorporated into the public agenda: decentralization, political participation, municipalization, judicial order reforms and the role of the State in a new economic strategy. The social reality of the country made the changes difficult to apply. Economic crises in the 1980s and 1990s led to a political crisis. Hundreds of people were killed by Venezuelan security forces and the military in the Caracazo riots of 1989 during the presidency of Carlos Andrés Pérez (1989–1993, his second term) and after the implementation of economic austerity measures. Hugo Chávez, who in 1982 had promised to depose the bipartisanship governments, used
