I want to know the answer to the following question:
Alexander the Great was the emperor of what?
All the background I'm provided with is that "After Alexander the Great's ventures in the Persian Empire, Hellenistic kingdoms were established throughout south-west Asia (Seleucid Empire, Kingdom of Pergamon), north-east Africa (Ptolemaic Kingdom) and South Asia (Greco-Bactrian Kingdom, Indo-Greek Kingdom).". Is that enough to answer the question?
