What was the Three Bandit Nations?

The Three Bandit Nations refers to a historical term used to describe three regions in East Asia—specifically, the states of Korea, Japan, and Mongolia—during a period marked by piracy and raiding activities. These regions were notorious for their maritime and land-based banditry, particularly during the late medieval and early modern periods. The term often highlights the complex interactions between these nations, including trade, conflict, and cultural exchange. It is important to note that the term is not widely used in contemporary discourse and may vary in interpretation based on historical context.
