Stoicism is one of the most influential schools of philosophy in Western history — founded in Ancient Greece, refined in Rome, and still widely practiced today. This page features an interactive Stoicism timeline designed to make Stoic history easy to understand and actually useful. You’ll see the major Stoic philosophers in order — Zeno of Citium, Cleanthes, Chrysippus, Seneca, Epictetus, and Marcus Aurelius — along with the key moments that shaped Stoic thought over time.

As you explore the timeline, you’ll learn how Stoicism evolved from a formal school taught at the Stoa Poikile into a practical framework for resilience, emotional regulation, and clear thinking under pressure. Each entry explains the context behind the ideas and highlights core Stoic concepts like virtue ethics, living according to nature, the dichotomy of control, and the role of judgment in shaping emotion. You’ll also see how Stoicism influenced later philosophy and modern approaches to mental training, including cognitive reframing and evidence-based psychology.

Use the search and era filters to focus on the period you care about most — Founding Stoicism, Old Stoicism, Middle Stoicism, Roman Stoicism, Stoicism’s legacy, or modern Stoicism. Whether you’re new to Stoic philosophy or deepening your practice, this Stoicism timeline gives you a clear, structured overview of where the ideas came from, how they changed, and what still matters now.
