The Second Seal is associated with the Roman period fraught with civil wars between would-be emperors that came and went during that time. It was the beginning of the end for the Pagan Roman Empire. When the Cretan Dynasty came to an end, this marked the beginning of Rome's downfall.
The Year of the Five Emperors refers to the year 193 AD, in which there were five claimants for the title of Roman Emperor: Pertinax, Didius Julianus, Pescennius Niger, Clodius Albinus and Septimius Severus. This year started a period of civil war where multiple rulers vied for the chance to become Caesar.
Year of the Five Emperors and subsequent civil war (AD 193–196), between the generals Septimius Severus, Pescennius Niger and Clodius Albinus following the assassination of Commodus (AD 192) and the subsequent murders of Pertinax and Didius Julianus (AD 193). Severus is victorious and founds the Severan dynasty.
Severus was declared Caesar by the Senate, but Pescennius Niger was hostile when he declared himself emperor. This started the civil war between Niger and Severus; both gathered troops and fought throughout the territory of the empire.
