Random Riddle: My Kingdom

There are over fifty members in my family;
Yet none quarrel. We all live merrily.

Four leaders have we, all with a bride;
Each has a son who has great pride.

We also have servants who make funny gestures;
But they are hardly used, as they often pester.

The peasants are at the bottom of the line;
Although they outnumber us, they haven’t a right mind.

What are we?
