The third wave began in the final years of the 1990s and continued into the 21st century. It overlapped in part with the pink tide of left-wing resurgence in Latin America. Like the first wave, the third made heavy use of Americanismo and anti-imperialism, although this time these themes presented alongside an explicitly socialist programme that opposed the free market. Prominent examples included Hugo Chávez in Venezuela, Evo Morales in Bolivia, Rafael Correa in Ecuador, and Daniel Ortega in Nicaragua. These socialist populist governments have presented themselves as giving sovereignty "back to the people", in particular through the formation of constituent assemblies that would draw up new constitutions, which could then be ratified via referendums. In this way they claimed to be correcting the problems of social and economic injustice that liberal democracy had failed to deal with, replacing it with superior forms of democracy.
