Which is the most extreme form of authoritarianism absolute monarchy dictatorship Junta or totalitarianism?

Answer 1

For all practical purposes all three of the named government disasters come down to the same thing. Each of the choices places extreme limits on a citizens civil rights. The fascism of Nazi Germany, or the Dictatorship of the Soviet Union by Stalin were both systems that made the "State" supreme over the individual, and the people who ran it were dictators of one sort or another. Of course as definitions of these horrible types of regimes would more easily produce a more detailed answer.
