Who accusations that Socrates faced when he was placed on trial?

Socrates was accused with "corrupting the youth." Basically, he would stand in the town square and find men high up in their respective professions then show that they really knew nothing at all about what they claimed to be experts about. The youth took to enjoying these encounters and became students of Socrates.

Those who were high up in society took offense and embarrassment to these encounters and decided Socrates needed to be put to death.
