Stele of Naram-Sin: a triangular stone with an army carved on it marching uphill

Stele of Naram-Sin

An empire is like a state, only with one more layer of government. States generally have at least four levels of administration; empires have five. An empire is generally made up of a lot of states joined together. Sometimes these states are still mostly independent, sometimes they are totally part of the empire. The usual pattern of empires is that one state, for whatever reason, becomes stronger than its neighbors and conquers them, creating an empire. The more it conquers, the stronger it gets, and so it conquers more and more of its neighbors. (There’s also the victorious army problem).

Eventually the empire stops growing. Sometimes  that’s because it meets neighbors who are stronger than it is. But more often it’s just because it is inconvenient to fight so far from home.

After some time, the empire weakens and breaks up into smaller states again. There’s really no need to explain why. It’s hard to hold an empire together, and any little problem can make it fall apart. Often, the empire hires weaker people living outside the empire as mercenaries, and then they end up invading or taking over. Sometimes they have to fight wars on two different borders at the same time, and they can’t afford it. Sometimes there’s a plague or a drought. Often the death of a leader leads t civil war. Sometimes there’s great inequality – a few very rich people and mostly very poor people – and that weakens the empire because very few people go to school, so they can’t invent things or organize things very well. Neighboring empires that have been more equal send more kids to school and develop better technology. Then they use their strength to attack unequal empires.

The first empires were probably in West Asia, first under the Akkadians, then under the Babylonians, and then under the Assyrians. The Egyptians also had a sort of empire in the New Kingdom as they conquered Israel, Jordan, Lebanon and Syria. China had empires a little later, under the Shang Dynasty.

The Hittites also had a small empire. These empires were mainly tribute-collectors. They did not try very hard to control the activities of the states under their control.

The Persian Empire in 539 BC, was different from any empire before it. It was more centrally controlled, thanks to good roads and a good messenger service. Like most later empires, the Persian Empire brought peace and safety. But some people who wanted to rule themselves were forced into the empire. The peace and safety of the Persian Empire and the Zhou Dynasty in China allowed increasing trade between them along the Silk Road.

Alexander the Great eventually took over the Persian Empire, but when he died it broke up into a number of smaller states. Further east in India, Chandragupta built the first Indian empire about the same time. After about 50 BC, West Asia was dominated by the Parthian and then the Sassanian Empire and the Mediterranean Sea by the Roman Empire.

In the 400s AD, the Roman Empire broke down into smaller states again. Then in the 600s AD the Arabs conquered much of the Roman Empire and all of the Sassanian Empire  and built them into the Islamic Empire.

The Islamic Empire, like other West Asian empires before it, has a pattern of unifying and collapsing which has lasted from then until now. In Europe, no medieval power after Charlemagne succeeded in building a successor to the Roman Empire, though many Holy Roman Emperors tried. The Aztecs and Incas in the Americas built smaller empires. But in the later Middle Ages, almost all of Eurasia – from Eastern Europe to China – was unified in one gigantic empire under Genghis Khan and the Mongols.

In the 1300s, the Mongol Empire collapsed too – partly because of the Black Death. But even bigger empires were on their way. In the Renaissance, the Holy Roman Empire and Great Britain formed huge colonial empires. Charles V controlled most of the Americas, and Britain controlled India, South Africa, and the Atlantic coast of North America.

But after the World Wars, these empires also broke up. In the 1900s, the world’s empires were the U.S.S.R. with a big empire across Central Asia, China controlling most of East Asia, and the United States with an empire made up of the fifty states. The collapse of the U.S.S.R. in the 1980s left China and the United States as the only big empires in the world today.
