Its object is to overthrow a regime and to set up a new regime in its place. In a revolutionary war both sides use force. Tyranny is armed. Otherwise it would be liquidated overnight. Certainly the use of force also wakens fear.
Tyrannous rulers begin to fear for their positions, or their lives, or both.
And consequently they try to sow fear among those they rule. But the installing of fear is not an aim in itself. Their words are usually foolish, as it supposedly depends on your point of view. I think of myself as a Resistance soldier and my Resistance fellow-travelers agree. If you do so, then you will have a substantial leg up in understanding your subject, and in writing a term paper which will be outstanding from among your contemporaries.
