Socrates was a classical Greek (Athenian) philosopher credited as one of the founders of Western philosophy, and as being the first moral philosopher, of the Western ethical tradition of thought. An enigmatic figure, he made no writings, and is known chiefly through the accounts of classical writers writing after his lifetime, particularly his students Plato and Xenophon.

Socrates lived during the time of the transition from the height of the Athenian hegemony to its decline with the defeat by Sparta and its allies in the Peloponnesian War. At a time when Athens sought to stabilize and recover from its defeat, the Athenian public may have been entertaining doubts about democracy as an efficient form of government. Socrates appears to have been a critic of democracy, and some scholars interpret his trial as an expression of political infighting.

In 399 BC, Socrates went on trial and was subsequently found guilty of both corrupting the minds of the youth of Athens and of impiety (asebeia, "not believing in the gods of the state"), and as a punishment sentenced to death, caused by the drinking of a mixture containing poison hemlock.
