The Roman emperor Domitian, who doesn't seem to look so much like his dad.

The Roman emperor Domitian, assassinated in 96 AD

When Domitian was assassinated in 96 AD, people were very much afraid that it would be like after the assassination of Julius Caesar, or after Nero’s suicide, and there would be another civil war. Quickly the Senate met and chose one of the senators to be emperor.

Nerva: a white man in a toga

The Roman emperor Nerva

They chose Nerva, who was an old man with no sons who might want to inherit the throne. Nerva didn’t have time to do much as emperor, because he died in 98 AD, after only two years in power, but he did start a new system for choosing the next emperor which worked better: he chose somebody who seemed like he would do a good job, and he adopted him as his son.

Trajan: a white man with straight hair and no beard

The Roman emperor Trajan (A.D. 98-117) in the Vatican.

The man Nerva adopted was Trajan. And Trajan did become emperor when Nerva died, and he did do a good job. Trajan took the Roman army to Dacia (modern Rumania), and he conquered it. Dacia had a lot of gold mines, and so Rome became rich from all the gold. Trajan also seems to have made Christianity illegal. Then Trajan took the army to West Asia, and he conquered a lot of land from the Parthians – all the way to Babylon, where Alexander had died! Trajan also had no sons, and he seems to have adopted his nephew as HIS son. The nephew’s name was Hadrian.

The Roman emperor Hadrian

The Roman emperor Hadrian

When Trajan died, Hadrian became emperor. Hadrian was not as popular as Trajan, because as soon as Trajan died Hadrian decided that the Roman Empire couldn’t really keep all that land Trajan had conquered in West Asia, and he gave most of it back to the Parthians.

He thought it would be too expensive to try to keep it, because it was so far away from Rome. Of course the army didn’t like giving up all this land they had fought for. And Hadrian didn’t try to conquer anyplace new either. The army got bored. Still, Hadrian did keep peace in the Roman Empire. Like Nerva and Trajan, Hadrian had no children, and he adopted a grown man with no sons, instead.

The Roman emperor Antoninus Pius

The Roman emperor Antoninus Pius

When Hadrian died in 134 AD, his adopted son Antoninus became emperor. Antoninus is often called Antoninus Pius because he was so interested in religion and in doing everything right. Like Hadrian, he didn’t fight any wars. But the Roman Empire stayed peaceful and everyone was doing pretty well. Again Antoninus Pius adopted a grown man to follow him, and that was Marcus Aurelius.
