After his father's death, Alexander continued his father's conquest and invaded Persia and Egypt. He marched his military towards the Indus Valley, but he was unsuccessful. On his way home, he was stricken with sickness and died in a few days. After his death, his empire was divided into three parts and there was a new shared culture between them. The Hellenistic culture was a blend of Greek, Persian, and Indian. This became known as the age of beauty, science, and math.
