Russia have such history and tradition with their rulers.
Russia also has a long tradition of democracy. Just for example, Republics of Pskov and Novgorod existed a long before the US even were formed. If we speak about the Empire, then courts were independent and judges were democratically elected for 3-year term.
If I remember well, nobody resigned or gave power to others in last 1000 years!
Then you definitely are suffering some memory issues.
Nicholas II - agreed to establish constitutional monarchy in 1905;
Nicholas II - resigned in 1917;
Grand Duke Michael - resigned in 1917;
Malenkov - impeached in 1955;
Khruschev - resigned in 1964 under a threat of impeachment;
Yeltsin - resigned in 1999;
Well, that I was able to remember in few minutes.
After all, there are no real opposition in Russia now.
There is a plenty of real oppositional powers, they're holding a significant share of seats in the parliament.
P.S. Liars like you have turned "democracy" into an obscene word.
