Social movements came to life again in Latin America towards 1964. Working mainly at the local level, they have been undergoing intense evolution by adopting political functions. This has been due to the concatenation of the problems faced by them in existing vacuums of power. Movements have sustained themselves in time and have expanded regionally, to the point of now adopting national stances. This is expressed in autonomous action exemplified in Brazil, Mexico, Colombia, Chile and other nations. Prospects are difficult because of repression and co-optation, but unexpected resistance of the movements expresses an intense desire to achieve alternative developments and ways of life in these countries.
