It's a false legend promoted by today's democratic governments.
In fact democracy in Ancient Greece wasn't how we know it today:
-It was only limited at the city of Athen
-Only adult rich men born in Athen with both the parents citizens of Athen could vote, in fact that was a minority
Most important
-People absolutely didn't like democracy, not who couldn't vote, they didn't care, but philosophers like Plato.

Yes because back then, India was a colony of England and basically owned by a company called the East India company with military enforcement. The people had no representation and also were forced to pay taxes such as the salt tax that ghandi famously went against during the salt March.
Likewise, the united states back then was also a colony of India and had no representation as well as had to pay taxes from laws such as the stamp act. Their values in fighting for independence and free reign were very similar. So yes.
