Where did the idea of advocacy come from?

The idea of advocacy dates back centuries, originating as a means for individuals or groups to support a cause, seek justice, or promote change. Advocacy can be traced as far back as ancient Greece, where philosophers like Plato and Aristotle engaged in debates and discussions to influence societal beliefs and decisions. It has since evolved into a key component of democracy, enabling citizens to voice their opinions, defend rights, and drive progress.
