ABSTRACT
This chapter analyzes the Unasur’s role as mediator in internal crisis of Bolivia (2008) and Ecuador (2010), and the inter-state conflicts of Colombia-Ecuador (2008) and Colombia-Venezuela (2009 and 2010). Likewise, its institutional entrepreneurship in the collective defense of democracy with the Georgetown Protocol of 2010 and, its counter-balance role during the US-Colombian military Agreement crisis (2009), which was a starting point for the creation of the South American Defence Council (SADC). Later, it analyzes Unasur’s decline due to Chávez’s death (2013), and the appeasement of the organization on the democratic backsliding in Venezuela (2014–2017). Its decline (2018–2019) confirms the fragility of Latin American multilateralism liable to political cycle changes. The rise of right-wing governments, less committed to political concertation at the multilateral level, generates Unasur’s dismemberment and the birth of the Forum for the Progress and Development of South America (Prosur) a weak project with the old multilateral practices of the Americas.
