Related to this question: After the main character united the seven clan into a Soviet-esque nation, education is introduced and critical, rational, and independent thinking is introduced to these seven warrior races. At the foundation of the nation, MC runs the nation as a paramount leader, assists by a council made of the Party Cadres (the foundation member of the Party, coming from the top echelon of each clan). MC is well-respected by all of the citizens because the MC gains the leadership of each clan fair and square and MC turn the nation from an early 19th century nation all the way into early 20th century in twenty years. But after a few decade, advocation for democracy starts to emerge from the young adults and people dissatisfy with the Party's policy being conservative and and the old ruling/social structure inadequate for the new world--because human nations are advancing too. After an incident, MC realized that grave mistakes are being made and a new government structure is needed for this nation (this is a character development plot). But how could the MC convince the Party Cadres to give up the power they once had without triggering something like the dissolution of Soviet Union or having tanks running over protesters?
Edit: The Party Cadres dont have inherent problem of loving power. They respect strength and believe that they are doing what is best for their nation. It is about the same sort of situation--in a more ideal way--as the 1989 Democratic movement in China. Basically, how to prevent the conservatives in the Party Cadres from anger overload and call in the tanks and convince them that they are wrong and the Party needs new Blood. Once again, they are not glory hound or power hungry.
