How did globular clusters form?

Answer 1

Often, they all form from one dense nebula that suddenly collapses due to external forces.

The forces caused by supernovae, a star passing by, or even colliding galaxies can disrupt the nebula and cause many stars to form at roughly the same time and in the same location.
