Chávez strengthened his support among the poor with a series of social initiatives known as the Bolivarian Missions, and created a network of grass-roots workers' councils, the Bolivarian Circles.[6] Nevertheless, by early 2002, Venezuela was "embroiled ... in a severe political crisis" as Chávez sought to bring more of the country's vast oil wealth under state control.[7] Although the state-owned radio and television stations remained staunch advocates of Chávez's stated policies—to redistribute the nation's wealth to the poorest—the private media was more hostile.[nb 2] The crisis reached a head when Chávez attempted to remove the management of the state oil company, Petróleos de Venezuela (PDVSA), provoking a showdown. "Oil managers, business leaders, and large segments of organized labor" called a general strike.[7] The strike was backed by a large segment of the population, "particularly the country's increasingly impoverished middle class" and army officers upset at the increasing politicization of the military.[7]
