Venezuela
Venezuela's modern history was shaped by a number of people, including President Romulo Betancourt, who replaced a military dictatorship with a democracy. By the 1970s, Venezuela had become rich off of oil revenue, but it had problems in the 1980s and 1990s. In 1999 Hugo Chávez became president and tried to remake Venezuela as a socialist state. While popular at first, the economic changes Chavez and the next president, Maduro, passed caused a massive economic depression in the mid-2010s. The current president is disputed.
