Archaic period the Persian Empire emerged and replaced the Assyrian Empire

This proposition is based on incorrect premises. During the ArchaicPeriod (which covered up to 600 BCE), Persia was not an empire, itwas a tribal confederation which was subject to Media. And theAssyrian Empire was over – its residue existed in the shadow of theBabylonian Empire.

From 550 BCE Persia absorbed Media, and used this combined strengthto absorb the Babylonian Empire. It then expanded further over thenext 50 years, under Kings Cyrus the Great, Cambyses and Darius theGreat, to incorporate Asia Minor, Central Asia, the rest of theMiddle East, Libya-Egypt and today’s Pakistan.
