The Triumphal Arch of Septimius Severus

Septimius Severus, born in 145 or 146 AD, was a Roman 'eques'. In the Middle Ages an eques would be called a 'knight' . He came from the African city of Leptis Magna. In 190 AD he became consul. After that, he was a senator. When Commodus, emperor of the Roman Empire from 180 till 192 AD, died, he was appointed governor and commander of the armies in Pannonia. Pannonia is roughly present-day Czechia.
Just after a four-year civil war, on the 13th of April 193 AD, he was acknowledged as the new emperor by his own armies. On the 9th of June he arrived in Rome without meeting considerable opposition. In 211 his successor was emperor Caracalla.
The Arch of Septimius Severus was built at the Roman Forum to commemorate the victories of Septimius Severus in the east. The different episodes of the war are described in great detail in the many reliefs, which decorate the monument.
