There are many different ways to define advocacy. Put simply, advocacy is a way of influencing a process or outcome so that it reflects your priorities. Advocacy can be done by an individual or in a group, it can be grassroots or large-scale, and can be applied to many different areas (e.g. international processes, national laws and policies, a school board). Advocacy usually targets decision-makers, like politicians or heads of organizations. It can, however, also be used to gain support more generally (like a public movement or campaign).
