Which Ancient Greek historian linked government types to military?

[Reichcube]

I remember having read a series of quotes from an ancient Greek historian or philosopher who attributed the form of each nation's government to the composition of their military.

He said Athens was a democracy because it had a large navy, Sparta was an oligarchy because it relied on heavy infantry and aristocracies were so because they relied on cavalry.

Does anyone know his name? And if possible, where did he say that?

An anonymous writer known as "Pseudo-Xenophon" or the "Old Oligarch", in a treatise called The Constitution of the Athenians.

Xenophon himself, of course wrote on the Constitution of the Spartans and Aristotle wrote on the Constitution of the Athenians, and they kinda insinuate the same point.

(He's called "Pseudo-Xenophon" because the work was traditionally believed to be written by Xenophon, and published in collections of Xenophon's works; although modern historians have come to believe it was not actually Xenophon, but some older anonymous guy who wrote it around 425 BCE - about a half-century before Xenophon, and nearly a century before Aristotle)
