That's a ringing endorsement; They weren't as bad as Stalin.I presume you are joking here, it was shocking what happened the romanov family. Yes they did not care about the suffering of the Russian serfs in the 19th century. But at this remove there is a lot more love for them than there is for the communists and Stalin among Russians now.
Serfs were slaves who were sold with the land they were attached to.
Despite what HBO would have us think the amount of Surfs increased under Catherine the Great. It was Alexander II, under the influence of his aunt, Grand Duchess Elena Pavlovna (a German, just like Catherine) who abolished Serfdom but the Serfs had to buy their way out of serfdom and remained poor and landless. It is not surprising that the Romanovs were killed. What is surprising is that it didn't happen sooner.
On a side note Catherine the Great allegedly shares a notable event with Elvis. Answers on a postcard.
