Since the mid-1980s, Latin America has seen an intense period of constitutional change, as almost all countries either adopted new constitutions (Brazil in 1988, Colombia in 1991, Paraguay in 1992, Ecuador in 1998 and 2008, Peru in 1993, Venezuela in 1999, and Bolivia in 2009, among others) or introduced major reforms to their existing constitutions (Argentina in 1994, Mexico in 1992, and Costa Rica in 1989). The new Brazilian constitution of 1988 can be viewed as the starting point of this phase of reforms, which is still developing. Obviously there are important national differences. However, despite these national differences, this wave of constitutional reforms in Latin America seems to have some common features.
