Cliodynamics is the study of how societies change and how they stay the same over time. It looks at patterns in history, like how societies form, how they grow and how they collapse. Cliodynamics tries to understand history and human behavior by looking at the dynamics and patterns of past events. It uses scientific methods, like mathematics and computer modeling, to find these patterns and make predictions about the future. It's like trying to read the past and the future in one go.
