Where details are known as to the inner workings of authoritarian regimes, we see conspiratorial interactions among the political elite not merely for preferment or favor within the regime but as the primary planning methodology behind maintaining or strengthening authoritarian power.
Authoritarian regimes give rise to forces which oppose them by pushing against the individual and collective will to freedom, truth and self realization. Plans which assist authoritarian rule, once discovered, induce resistance. Hence these plans are concealed by successful authoritarian powers. This is enough to define their behavior as conspiratorial.
