The problem here is that, in both cases, a great variety of periods are given the labels of Persian Empire and Assyrian Empire, when in fact there were periods of small area coverage or different rulers and influence by the basic ethnic peoples and the ruling classes, which were sometimes foreign. And this line of thought often entwines both peoples as if they were the same at some periods. 'Persian Empire' has been applied spasmodically to periods between 627 BCE to 1979 CE, while similarly Assyrian Empire' has been used to label periods from 25th Century BCE to 627 CE.
The main periods were Persia 549 to 330 BCE; Assyria 991 to 627 BCE. But there will be many people who will claim all sorts of periods outside that so where do you go?
Assurbanipal (or Ashshurbanipal) was the last strong king of the Neo-Assyrian Empire.
Artaxerxes V.
Darius III.
No, the Persian Empire did not last from 1500 BC to 185 BC. The Persian Empire, also known as the Achaemenid Empire, was established in 550 BC and lasted until it was conquered by Alexander the Great in 330 BC.
It lasted for so long because the Assyrians were absolutely ruthless in subjecting and controlling the peoples living in their Empire. That Empire fell apart when after the death of King Ashurbanipal in 627 BC, three rivals for the throne went at each other's throats in a series of civil wars. This gave many subject peoples the opportunity to detach themselves from the Empire. The Persian and Babylonian Empires then formed a coalition to make themselves masters of what remained of the Assyrian Empire.
550 to 330 BCE.
from oldest to most recent, it is the akkadian empire, then the babylonian empire, then the assyrian mpire, and last but not least, it is the neo-babylonian empire
550-330 BCE - 220 years.
ca. 550 BCE-336 BCE
It was defeated by Macedonia under Alexander the Great who took it over as an empire of his own.
The Civilization that defeated Egypt, was the Persian Empire or also known as the Achaemenid Empire. The Persian Empire defeated the Egyptians while Cyrus The Greats Son (Cambyses II) was reigning over the Empire. The Egyptians didn't even bother to try and stop the Persian Empire as they we sick of their previous ruler. So I think the answer you are looking for is the Achaemenid Empire. Although they did capture Egypt, after the Persian Empire finished, all of the empire broke up into lots of different countries, as this was when the Persian Empire Fell.Hopefully This Helped.
