Edward Gibbon (1737-1794) called the loss of independence and excessive obedience to the Emperor the "secret poison" which corrupted the Roman Empire:
Politics & Liberty
It was scarcely possible that the eyes of contemporaries should discover in the public felicity the latent causes of decay and corruption. This long peace, and the uniform government of the Romans, introduced a slow and secret poison into the vitals of the empire…Their personal valour remained, but they no longer possessed that public courage which is nourished by the love of independence, the sense of national honour, the presence of danger, and the habit of command. They received laws and governors from the will of their sovereign, and trusted for their defence to a mercenary army. The posterity of their boldest leaders was contented with the rank of citizens and subjects.
