Chávez's version of Bolivarianism, although drawing heavily from Simón Bolívar's ideals, was also influenced by the writings of Marxist historian Federico Brito Figueroa. Chávez was also thoroughly steeped in the South American tradition of socialism and communism early in his life, such as that practiced by Jorge Eliécer Gaitán, Fidel Castro, Che Guevara and Salvador Allende. Other key influences on Chávez's political philosophy include Ezequiel Zamora and Simón Rodríguez. Although Chávez himself refers to his ideology as Bolivarianismo ("Bolivarianism"), Chávez's supporters and opponents in Venezuela refer to themselves as being either for or against "chavismo". Chávez supporters refer to themselves as "chavistas."
Later in his life, Chávez would acknowledge the role that democratic socialism (a form of socialism that emphasizes grassroots democratic participation) plays in Bolivarianism. For example, on January 30, 2005 at the World Social Forum in Porto Alegre, Brazil, Chávez declared his support for democratic socialism as integral to Bolivarianism, proclaiming that humanity must embrace "a new type of socialism, a humanist one, which puts humans, and not machines or the state, ahead of everything. He later reiterated this sentiment in a February 26 speech at the 4th Summit on Social Debt held in Caracas.
The Colombian insurgent group FARC has, in recent years, also considered itself to be inspired by Bolívar's ideals and by his role in the 19th century independence struggle against Spain. It has also publicly declared its sympathy towards Hugo Chávez and his Bolivarian Revolution, both of which do not actively confirm or deny any involvement with the insurgent group. It is known that some individual Venezuelan bolivarianos do actively sympathize with the FARC in return, but it is not an automatic occurrence.
A Venezuelan guerrilla organization, the Bolivarian Forces of Liberation, also espouses Bolivarianism, although it is not known if there are any ties to the Venezuelan government.
It is also worthy of notice that, while many Bolivarianists often include Brazil in their plans for unification and integration of South America, this is mostly unknown among Brazilians or widely regarded as a foreign movement, particularly due to the language difference and the fact that not all Brazilians see Brazil as a Latin American country.
Several political parties in Venezuela support chavismo. The main party, directly affiliated with Chávez, is the Fifth Republic Movement (Spanish: Movimiento Quinta Republica, usually referred to by the three letters, MVR). Other parties and movements supporting chavismo include Fatherland for All (Spanish: Patria Para Todos or PPT), and Tupamaros.
The left-wing Movement for Socialism (Spanish: Movimiento al Socialismo or MAS ), Radical Cause (Spanish: Causa R) and For Social Democracy (Spanish: Por la Democracia Social) initially supported chavismo, but they have since distanced themselves from it, and now oppose it. For Social Democracy is the latest party to oppose this movement.
A 2002 article in The Boston Globe said chavismo "fueled the eruption of public fury that swept the charismatic and confrontational president back into power after a group of military officers deposed him for two days in April in favor of a businessman-president," adding that the "Chavismo phenomenon has almost religious qualities.
Writing in The Weekly Standard, Thor Halvorssen says that "At [Chavismo's] core is a far-reaching foreign policy that aims to establish a loosely aligned federation of revolutionary republics as a resistance bloc in the Americas. The Chavista worldview sees the globe as a place where the United States, Europe, and Israel must be opposed by militarized one-man regimes."
According to an article in the New York Sun, Chavezism was rejected in recent elections in Peru, Colombia and Mexico, and El Universal reports that Brazilian President Luiz Inácio Lula da Silva distanced himself from Chavezism, saying that Brazil is not Venezuela, and has traditional institutions.
On early May 2008, German Chancellor Angela Merkel declared that "President Chavez does not speak for Latin America. Every country has its own voice with which it pursues its own interests." prior to embarking on a one-week Latin America trip that took her to Brazil, Colombia, Mexico and lastly Peru, where the European Union-Latin America summit took place the week starting May 18, a statement which brought an immediate aggressive response from Venezuela's president, and some minor attached consequences.
