In ancient times, the king's position was hereditary and the comman man had nothing to do with it but had to accept whatever the king says, even if it is right or wrong.
Now, in modern times, we have a democratic country and it is the common man who elects the President, Prime Minister, Chief Minister etc. of our country.
To say in short, Before, the Common man was nothing but a common man,
Now, the common man plays a very important role in our country.
