By the 18th century the Kingdom of Great Britain was already a constitutional monarchy. George III was sitting on the throne through much of this century, and could be considered an enlightened monarch, but typically is not included as he wasn't really a proper despot.
I will not call Erdogan an angel, but I don't think he repressed more people that Ataturk did. Anyway, this quiz is by nature controversial. One may even call Hitler was englighted depending on their definition.
I know what Enlightenment is but I didn't know enlightened dictator was necessarily linked to it. I thought it was generic like "acting according to noble principles". That's why I voluntarily used a weird example. My bad.
I didn't say Ataturk didn't do anything good but I wanted to point out the fact that he didn't truly advocate for freedom of speech and freedom of religion, which are fundamental rights. Enlightenment was never about forcing people to act according to your opinions because you think you know better than them. One may find many examples of Ataturk going against the 6 points you mentioned, especially 1-4.
Also, it's important to note that the first and fourth Caliphs after Muhammad were directly elected by their peers, and all four of the "rightly-guided" (with the possible exception of Ali) were unanimously accepted by their subjects through the system of "bay'ah", a kind of proto-voting system.
I'm also rather surprised that no one has brought up Napoleon Bonaparte, especially regarding Napoleonic Code, which may be the epitome of Enlightenment ideals. Ditto for Napoleon III, who was perhaps even more benevolent than his uncle without the bloodthirstiness.
