The term most closely associated with Hellenism under Alexander the Great is "cosmopolitanism." This refers to the blending and diffusion of Greek culture and ideas across the vast territories conquered by Alexander and the establishment of cities that reflected a fusion of Greek and local cultures. Hellenism under Alexander's influence was characterized by the spread of Greek language, art, philosophy, religion, and political systems throughout his empire, which extended from Greece to Egypt, Persia, and India. The result was a hybrid culture that became a model for subsequent empires and influenced the development of Western civilization.
