Emperor Sujin vs Pertinax

Emperor Sujin is recorded in the Nihon Shoki as having organized the Yamato state, establishing administrative structures and military garrisons. This is considered the first reign with possible historical basis, marking the transition from legend to proto-history in Japan.

According to the Nihon Shoki, Emperor Sujin dispatched generals to suppress rebellions in various regions of Japan. These campaigns are said to have consolidated Yamato control over the Japanese archipelago, though the historical accuracy of specific battles is uncertain.

Emperor Sujin is credited with establishing the Ise Grand Shrine, dedicated to the sun goddess Amaterasu. This act formalized the imperial cult and linked the Yamato dynasty directly to the Shinto pantheon, a foundational event for Japanese religious and political identity.

Pertinax attempted to restore discipline to the Praetorian Guard and reform the imperial finances. He reduced taxes, sold off Commodus's extravagant possessions, and tried to curb corruption. These reforms alienated the Praetorian Guard, who expected a large donative.

Pertinax was proclaimed Roman emperor by the Praetorian Guard after the assassination of Commodus. He was the son of a freedman and had a distinguished military and political career. His accession was initially welcomed by the Senate and people as a return to good governance.

After only 87 days in power, Pertinax was assassinated by the Praetorian Guard. The Guard stormed the imperial palace and killed him because he refused to pay them the promised donative. His death triggered a civil war and the auctioning of the empire to Didius Julianus.
