But isnt assimilating serveral cultures into one by definition destroying most of them ??
Assimilation means people are forced to give up their old traditions, lifestyles, beliefs, etc; and pick up that of a new culture. They arent aloud to bring anything from theyre previous life with them, but become completely and without question a member of the new culture. By this process, the original culture is lost, or destroyed, and the new culture is all that exists.
Thus, if Alexander tried to assimilate all these cultures into his, he destroyed all those other cultures.
