Aristotle defined tyranny as an illegitimate form of government by one individual that tightly controlled every part of life and government

The statement is correct.

Explanation:

For Aristoteles, tyranny was the concept contrary to democracy. In this vision, tyranny was the government in which an individual, the tyrant, came to power through illegitimate and violent means and imposed a dictatorship. In this sense, tyranny was in the antipodes of the concept of democracy, in which all the free men of the polis participated in the assemblies and decided the destinies of the same.

In tyranny, the tyrant violently acceded to government, but unlike the modern concept of tyranny, it was not necessary for him to continue to exercise such violence against the people in order to continue to be considered as such.
