Axial Age civilizations

Axial Age (also Axis Age, from the German Achsenzeit) is a term coined by the German philosopher Karl Jaspers. It refers to broad changes in religious and philosophical thought that occurred in a variety of locations from about the 8th to the 3rd century BC. According to Jaspers, during this period, universalizing modes of thought appeared in Persia, India, China, the Levant, and the Greco-Roman world, in a striking parallel development, without any obvious admixture between these disparate cultures.
