Re: the comment that the Reformation traded one greedy body, the Catholic Church of the time, with another, the Monarch/"your favorite term here", no argument there. Little doubt the Swedish King favored the Reformation because it gave him the access to the riches formerly held by the Catholic Church in the lands he, Gustav (I of Sweden) Vasa, considered his. Nevertheless, the reformation did succeed in that it replaced the language of the Gospel with vernacular, not just in Northern Europe but also, as a counter-reformation, in the trad. Catholic countries.
This, maybe even somewhat against the interests of the Christian catholic Church, introduced the concepts of "ecucation" and "understanding". People no longer depended on the Catholic priest to "interpret" the Bible, the Gospel, but they (ok, slowly but still) could read & judge for themselves. To cut some corners, it lead to education. It lead to written (vernacular) languages, Bible translations. In Finland, for decades, one could not get married unless one could read Luther's Small Catechism. That is a pretty powerful incentive! If the license to marry = license to have sex --> to be able to read/literacy = to be able to enjoy free sex.
Re: the Tsar vs. Lenin/Stalin. When it came to forced deportations, labour camps, political prisoners, the "Soviets" certainly merely copied & pasted the Tsars' old notebooks, although the global mechanic industrialization made it more "effective," if you will. Interestingly, though, when the former Swedish province of Finland exchanged hands and became the (Russian) autonomous Grand Duchy of Finland in 1809, it was the time Finland finally made grand strides in political and infrastructural terms in the road to become the world's most democratic & efficient democracies, culminating in the Finnish parliamentary election in 1907 with the world's first universal sufferage. Finnish women not only did get the right to vote (as in New Zealand in 1893) but were in fact the first women in the world to get the right to stand as actual candidates in the election. In total, 19/200 Finnish female MPs were elected. This happened under Tsar Nicholas II (Nikolay Alexandrovich Romanov).
Then again, on 15 November 1917, the Bolsheviks declared a general right of self-determination, including the right of complete secession, and Finland followed suit. The same day the Finnish Parliament issued a declaration of independence. It was Lenin's Soviet government who first hurried to recognize the Finnish independence.
So, comparing the Tsarist Russia to the USSR is like comparing the two sides of the coins to each other. So maybe the communist Soviets actually managed to kill more lives than the Tsarist Russia, but it wasn't because of the lack of effort on the Russian Tsar's side; rather; it was that the mass killing machinery itself had advanced in great leaps during Lenin's/Stalin's years. On the other hand, both the Tsar and the politburo recognized realpolitik when they saw it: if it was much easier to give the taciturn Finns as much independence as possible to keep them manageable lest they became real pests and thorns-in-the side of the great motherland, then neither were above of granting just that. And PM Putin, on his part, resembles more of the authoritarian Tsar than the totalitarian USSR/CCCP.
