Who was Marcus Aurelius?

Marcus Aurelius (121–180 AD) was a Roman emperor who ruled for about 19 years and is remembered today mostly for his private journal, later published as "Meditations". In it he returned again and again to a Stoic idea: we cannot control what happens to us, only how we respond. That idea of self-control inspired a Little Keys story.

📝 The story behind the little key

An emperor and a student

Marcus Aurelius became Roman emperor in 161 AD and led through wars, plague, and constant pressure — while privately studying Stoic philosophy, a school of thought focused on virtue, reason, and self-control.

Meditations

Throughout his reign he kept a private notebook of reflections, writing to himself as reminders of how to live well. Published long after his death as "Meditations," it has become one of the most widely read works of philosophy ever written.

What is in our control

A central Stoic idea he returned to constantly is that events themselves are not in our power, only our responses to them — and that a calm, steady life comes from letting go of what we cannot change and acting well on what we can.

The Llama and the Lesson of Self-Control

🔑 How this connects to their story

Ludo the llama learns to sort his troubles into two piles — what he can control and what he can't — and pour his energy only into the first. That sorting is the heart of the Stoic philosophy Marcus Aurelius wrote about nearly two thousand years ago.
