2nd-century Roman emperors

16th Roman Emperor from 161 to 180 and Stoic philosopher

Trajan ( ; born Marcus Ulpius Traianus, 18 September 53) was a Roman emperor from AD 98 to 117, remembered as the second of the Five Good Emperors of the Nerva–Antonine dynasty. He was a philanthropic ruler and a successful soldier-emperor who presided over one of the greatest military expansions in Roman history, during which, by the time of his death, the Roman Empire reached its maximum territorial extent. He was given the title of optimus princeps ('the best ruler') by the Roman Senate.

Hadrian ( ; born Publius Aelius Hadrianus, 24 January 76 – 10 July 138) was Roman emperor from 117 to 138. Hadrian was born in Italica, in the present-day Andalusian province of Seville in southern Spain, an Italic settlement in Hispania Baetica; his gens Aelia came from the town of Hadria in eastern Italy. He was a member of the Nerva–Antonine dynasty.

Roman emperor from 193 to 211

Marcus Aurelius Antoninus (born Lucius Septimius Bassianus, 4 April 188 – 8 April 217), better known by his nickname Caracalla (; ), was Roman emperor from 198 to 217 AD, first serving as nominal co-emperor under his father and then ruling alone after 211 AD. He was a member of the Severan dynasty, the elder son of Emperor Septimius Severus and Empress Julia Domna. Severus proclaimed Caracalla co-ruler in 198, doing the same with his other son Geta in 209. The two brothers briefly shared power after their father's death in 211, but Caracalla soon had Geta murdered by the Praetorian Guard

Commodus (; ; 31 August 161 – 31 December 192) was Roman emperor from 177 to 192, first serving as nominal co-emperor under his father Marcus Aurelius and then ruling alone from 180. Commodus's sole reign is commonly thought to mark the end of the Pax Romana, a golden age of peace and prosperity in the history of the Roman Empire.
