What is the difference between Agile and DSDM?

Agile is an 'umbrella' term to represent a multitude of approaches, practices, and methods that are based upon the Agile principles contained within the Agile Manifesto. DSDM is a specific Agile approach which was designed to manage Agile projects because until that point, all Agile methods were purely development methods and did not contain any broader project management focus. DSDN set out to incorporate a project management approach into Agile environments.
