Stoicism is a philosophical school founded by Zeno of Citium around 300 BCE in ancient Greece. Its main principles emphasized living in harmony with nature, using reason, and practicing virtue as paths to achieving eudaimonia, or human flourishing. These ideas became popular in Roman culture, influencing the thoughts and actions of important thinkers throughout the empire.
