In 399 BCE, the Athenian philosopher Socrates was put on trial on charges of impiety (asebeia) against the pantheon of Athens and corrupting the youth of the city. Following a trial before 500 jurors, he was found guilty and sentenced to death by drinking a hemlock-based poison. This event, chronicled by his student Plato in works such as "Apology" and "Phaedo," has become one of the most famous trials in ancient history and marked a significant moment in Western philosophical tradition.
