I am restarting Plato’s The Republic. I’ve read through it partly before, but that was too long ago so i restart now. But I do know his conclusion is that philosophers should be in charge. This is similar to the idea of a “benevolent dictator”, no? The nice smart guy with no ill will has supreme control and everything will be alright is the idea.
I seem to remember that there was at least one Emperor of Rome who was a philosopher, who governed well and relatively benevolently. The was a series of "good" Emperors:
The Five Good Emperors of Rome were a group of emperors who ruled the Roman Empire from 96–180 CE:
Nerva: Ruled from 96–98 CE, Nerva was the first of the Five Good Emperors. He was a senator and member of the imperial court before becoming emperor. His reign was brief, but he brought stability to the empire after Domitian's assassination.
Trajan: Ruled from 98–117 CE.
Hadrian: Ruled from 117–138 CE. He was an active emperor who spent much of his time outside of Italy. His reign was relatively peaceful, though it was marked by the Jewish revolt.
Antoninus Pius: Ruled from 138–161 CE.
Marcus Aurelius: Ruled from 161–180 CE.
Marcus Aurelius Antoninus (Latin:
[ˈmaːrkʊs au̯ˈreːliʊs antoːˈniːnʊs]; English:
/ɔːˈriːliəs/ or-EE-lee-əs;
[2] 26 April 121 – 17 March 180) was
Roman emperor from 161 to 180 and a
Stoic philosopher. He was a member of the
Nerva–Antonine dynasty, the last of the rulers later known as the
Five Good Emperors and the last emperor of the
Pax Romana, an age of relative peace, calm, and stability for the
Roman Empire lasting from 27 BC to 180 AD. He served as
Roman consul in 140, 145, and 161.

However, here is the evaluation of his son and successor, Commodus.
Biological sons of the emperor, if there were any, were considered heirs;
[299] however, it was only the second time that a "non-adoptive" son had succeeded his father, the only other having been a century earlier when
Vespasian was succeeded by his son
Titus. Historians have criticized the succession to Commodus, citing Commodus's erratic behaviour and lack of political and military acumen.
[298] At the end of his history of Marcus's reign, Cassius Dio wrote an
encomium to the emperor, and described the transition to Commodus in his own lifetime with sorrow:
[300]
[Marcus] did not meet with the good fortune that he deserved, for he was not strong in body and was involved in a multitude of troubles throughout practically his entire reign. But for my part, I admire him all the more for this very reason, that amid unusual and extraordinary difficulties he both survived himself and preserved the empire. Just one thing prevented him from being completely happy, namely, that after rearing and educating his son in the best possible way he was vastly disappointed in him. This matter must be our next topic; for our history now descends from a kingdom of gold to one of iron and rust, as affairs did for the Romans of that day.
–Dio lxxi. 36.3–4
[300]
Here is what happened under Commodus:
Commodus (
/ˈkɒmədəs/;
[4] 31 August 161 – 31 December 192) was a
Roman emperor who ruled from 177 until his assassination in 192. For the first three years of his reign he was co-emperor with his father
Marcus Aurelius. Commodus' sole rule, starting with the death of Marcus in 180, is commonly thought to mark the end of a golden age of peace and prosperity in the history of the
Roman Empire (the
Pax Romana).
Commodus accompanied his father during the
Marcomannic Wars in 172 and on a tour of the Eastern provinces in 176. The following year, he became the youngest
emperor and
consul up to that point, at the age of 16. His solo reign saw less military conflict than that of Marcus Aurelius, but internal intrigues and conspiracies abounded, goading Commodus to an increasingly dictatorial style of leadership. This culminated in his creating a deific
personality cult, including his performances as a
gladiator in the
Colosseum. Throughout his reign, Commodus entrusted the management of affairs to his palace chamberlain and praetorian prefects, namely
Saoterus,
Perennis and
Cleander.
Commodus was assassinated by the wrestler
Narcissus in 192, ending the
Nerva–Antonine dynasty. He was succeeded by
Pertinax, the first claimant in the tumultuous
Year of the Five Emperors.

My point is there is a danger of becoming dictatorial and repressive if you are an emperor, but it doesn't always happen. It depends on the circumstances and character of the individual ruling. Marcus Aurelius Antoninus made a mistake in allowing his son to be Emperor.
