How did Socrates influence the world history?

Thousands of years ago,Socrates was the 1st philosofer to sacrifice his own life in order to prove that democracy is much more powrful than a private person.And by democracy we meen the power of DIMOS ,the people.

Socrates had his own ideas,he fought for them (in speech) but when more people than his single person decided he should die,he executed this order by taking himself the "konion" , a poison used in ancient Athens.
