Abstract: Over the last three decades, research on globular clusters (GCs) has uncovered an unexpected complexity: multiple stellar populations (MPs) within systems once thought to be simple, single-generation objects. In this talk, I will trace the evolution of this field—highlighting pivotal findings from chemical abundance studies, photometric splits, and extensive ground‐ and space‐based surveys—and illustrate how they have transformed our view of GC formation and evolution. Moving from this historical overview, I will present the latest dynamical and kinematic insights that reveal how different stellar generations intermix, migrate, and respond to the Milky Way’s tidal forces. Finally, I will outline promising directions for future research, including next‐generation spectroscopic surveys, advanced simulations of cluster self‐enrichment, and opportunities afforded by upcoming observational facilities.
