What lesson did 16th century Europeans take from the success and structure of the Ottoman Empire?
That one should send the men of fighting age from the subject people to fight in foreign wars, and that the subject population must be disarmed, humiliated and debased, made to move around, and impoverished by taxation.
"Mutual distrust should be stirred up among them by secret agents; their prominent families should be prevented from intermarrying; and their leaders should be disinherited or transported. All gatherings should also be forbidden: after all, did not the Sultan prohibit the ringing of church bells throughout his dominions?"
