Hadrian's relationship with the teenage boy Antinous raised eyebrows even in permissive Ancient Rome. His relationship with the Jews raises eyebrows even today.

Hadrian's reign got off to a rough start following the political murders of four ex-consuls. The new Emperor would eventually settle in though and set out on his first grand tour of the Empire in 121.

Though Hadrian's career had long been guided by Trajan, when the Emperor died in 117 he still had not named Hadrian heir.

Trajan greatly improved the infrastructure of the Empire and finished his reign by conquering much of the Middle East.

After Trajan ascended to the throne in 98 AD he fought two wars against the Dacians, finally annexing the country in 106 AD.

Nerva's brief reign was stormy, but his choice of Trajan as heir was inspired.

After Saturninus's revolt in 89 AD, Domitian's paranoia increased. In 96 AD court officials afraid for their lives conspired to have the Emperor killed.

Domitian attempted to emulate Augustus, but his heavy-handed treatment of the Senate earned him many enemies. Meanwhile, his focus on frontier defense brought charges of cowardice and his treaty with the Dacians was seen as a humiliation.

Domitian had spent his life in the background, but in 81 AD he found himself Emperor and soon demonstrated that he had very strong ideas about how to wield power.

Titus succeeded his father to the throne in 79 AD, but ruled for only two years before dying of a sudden infection in 81. Throughout the reign of the Flavians, Agricola campaigned in Britain to Romanize the island.
