2005–2019 Morales presidency

Evo Morales won the 2005 presidential election with 53.7% of the votes in Bolivian elections. On 1 May 2006, Morales announced his intent to re-nationalize Bolivian hydrocarbon assets following protests which demanded this action. Fulfilling a campaign promise, on 6 August 2006, Morales opened the Bolivian Constituent Assembly to begin writing a new constitution aimed at giving more power to the indigenous majority.

2009 marked the creation of a new constitution and the renaming of the country to the Plurinational State of Bolivia. The previous constitution did not allow a consecutive reelection of a president, but the new constitution allowed for just one reelection, starting the dispute if Evo Morales was enabled to run for a second term arguing he was elected under the last constitution. This also triggered a new general election in which Evo Morales was re-elected with 61.36% of the vote. His party, Movement for Socialism, also won a two-thirds majority in both houses of the National Congress. By 2013, after being reelected under the new constitution, Evo Morales and his party attempted a third term as President of Bolivia. The opposition argued that a third term would be unconstitutional, but the Bolivian Constitutional Court ruled that Morales' first term under the previous constitution did not count towards his term limit. This allowed Evo Morales to run for a third term in 2014, and he was re-elected with 64.22% of the vote. During his third term, Evo Morales began to plan for a fourth, and the 2016 Bolivian constitutional referendum asked voters to override the constitution and allow Evo Morales to run for an additional term in office. Morales narrowly lost the referendum; however, in 2017 his party then petitioned the Bolivian Constitutional Court to override the constitution on the basis that the American Convention on Human Rights made term limits a human rights violation. The Inter-American Court of Human Rights determined that term limits are not a human rights violation in 2018; however, once again the Bolivian Constitutional Court ruled that Morales has permission to run for a fourth term in the 2019 elections, and this permission was not retracted. "he country's highest court overruled the constitution, scrapping term limits altogether for every office. Morales can now run for a fourth term in 2019 – and for every election thereafter."

The revenues generated by the partial nationalization of hydrocarbons made it possible to finance several social measures: the Renta Dignidad (or old age minimum) for people over 60 years old; the Juana Azurduy voucher (named after the revolutionary Juana Azurduy de Padilla, 1780–1862), which ensures the complete coverage of medical expenses for pregnant women and their children in order to fight infant mortality; the Juancito Pinto voucher (named after a child hero of the Pacific War, 1879–1884), an aid paid until the end of secondary school to parents whose children are in school in order to combat school dropout, and the Single Health System, which since 2018 has offered all Bolivians free medical care.

The reforms adopted made the Bolivian economic system the most successful and stable in the region. Between 2006 and 2019, GDP grew from $9 billion to over $40 billion, real wages increased, GDP per capita tripled, foreign exchange reserves rose, inflation was essentially eliminated, and extreme poverty fell from 38% to 15%, a 23-point drop.
