Around the 1960s, political psychology was developed as a field of knowledge that attempted to interrelate scientific psychology and political phenomena. However, social and academic conditions are very different today. More and more, political psychology is becoming a protagonist, as much in the internal context of psychology as in the external context of its relations with the social world. Thus, political psychology can now be seen as a resource relating psychological knowledge to social practice, and relating psychological processes to social action. Political psychology is the interface that puts psychology and society in contact. The development of political psychology in Spain provides an example of this alternative view of the field.
