The terms were interchangeable back in the Cold War, everywhere outside academia; and there are interesting continuities between the Tsars and the Soviets. &quot;Glasnost&quot; and &quot;perestroika&quot; were first used in reference to Peter the Great&#x27;s policies, and Great Russia (Russia proper) was known as Red Russia as far back as, I think, the 1400s.<p>Also: _The Structures of Everyday Life_ and _Simplicius Simplicissimus_ both touch on Russia, in ways that suggest that the country (post-Mongol-conquest) always did have a certain amount of proto-Sovietness to it -- alcohol sales as a state monopoly, for example, or arms always coming from royal treasuries.
