This document provides an overview of Alexander the Great and the spread of Hellenistic culture. It discusses how Philip II united Macedonia and conquered Greece, paving the way for his son Alexander to expand the empire. Alexander then conquered the Persian Empire and continued eastward until his army grew tired. When Alexander died at age 32, his empire broke into three territories between his generals. This resulted in the blending of Greek, Egyptian, Persian and other cultures into Hellenistic civilization.
