There seems never to have been a civilization without toys, but when and how they developed is unknown. They probably came about just to give children something to do.In the ancient world, as in today's world, most boys played with some form of toy and most girls with another. In societies where social roles are rigidly determined, boys imitate their play after the activities of their fathers and girls after the tasks of their mothers. This is true because boys and girls are being prepared, even in play, to step into the roles and responsibilities of the adult world.What is remarkable about the history of toys, is not how they changed over the centuries, but how they remained the same.

Variations depended on local customs and ways of life because toys imitate their surroundings. Nearly every civilization had dolls, little weapons, toy soldiers, tiny animals and vehicles.Because toys can be regarded as an art form，they have not been subjected to technological leaps that characterize inventions for adult use.
