Puppetry is a very ancient form of theatre which was first recorded in the 5th century BC in Ancient Greece. Some forms of puppetry may have originated as long ago as 3000 years BC. Puppetry takes many forms, but they all share the process of animating inanimate performing objects to tell a story. Puppetry occurs in almost all human societies where puppets are used for the purpose of entertainment through performance, as sacred objects in rituals, as symbolic effigies in celebrations such as carnivals, and as a catalyst for social and psychological change in transformative arts.
