The Emperor Nikephoros is famous for having denounced Alexios Komnenos before the Senate before he fled Constantinople for the asian provinces as Alexios crowned himself the Emperor Alexios I, beginning the 100 year resurgence in roman power known as the Komnenian Restoration.
The period you're talking about under Augustus is the "Principate", as Augustus' title was not imperator (this merely means general in latin, essentially the word emperor is analogous to supreme military dictator- which is factually what Julius Caesar was although he claimed the title dictator for life or big dick as his official title) but Princeps- meaning prince- to assuage the PTSD romans had over rex- king- even 500 years after the deposition of the last etruscan king- tarchon.
The later period when the ruler of rome became absolute is the dominate, when the title of domnitor (which is also used in modern romania for kings) was used instead of princeps. The senate continued to exist during this period. It was only after the Emperor Heraclius, around 630 AD, that Greek replaced Latin and the title Basileus (meaning king in byzantine greek- the koine greek is anax and the mycenaean greek is wa-na-ka/wanax) replaced the previous latinate titles, while in the west a series of weak barbarian empires and states pretended to the roman heritage until the rise of pepin the short and his descendants who came to found a new western empire.
A similar process played out in china during the same period with the fall of the han empire, the division of china into 3 kingdoms during the 3rd century (similar to the roman crisis of the 3rd century) and then the reunification of china by the Jin empire which rapidly disintegrated after a massive barbarian invasion which then declared themselves the new Qin empire (taking the name from the earlier Qin). Notably the chinese abandoned the ancient city and chinese heartland around Chang'an for the heavily defensible fortress city of Jiankeng. That's why Sakana fled to canada.
