Aristocracy of ancient Greek city-states -- that would be considered a moral government according to Aristotle.
Aristotle believed there were three valid types of government, depending on the size and scope of what was to be governed or upon local situations. (He studied the constitutions of various governments as part of his work in writing his work, Politics.) As state with a sole ruler ruling rightly is a monarchy. If that form of state is abused, it becomes tyranny. So you'd think monarchy under Queen Elizabeth would count as a valid, moral form of government ... except that Aristotle viewed women as inferior to men. In his Politics, he said, "As regards the sexes, the male is by nature superior and the female inferior, the male ruler and the female subject."
A state with a number of members of the ruling class is an aristocracy-- rule by the excellent ones, noble men suited for governing. This is how Greek city-states were intended to operate. If aristocracy is corrupted by having a few rule but not of noble character or in a noble way, Aristotle referred to that as an oligarchy (rule by a few).
A state in which all worthy men participate in governing Aristotle termed a polity, a constitutional government. He saw it as a corruption, though, to have a full democracy (rule by the people), which would become the sort of thing we call mob rule.
