The purpose of an advocacy group is to represent specific interests, values, or causes within the political arena. These organizations mobilize support, raise awareness, and influence policy by engaging in activities such as lobbying, conducting research, and organizing campaigns. Advocacy groups can operate on local, national, or international levels, focusing on issues ranging from environmental protection to social justice. By providing a voice for marginalized communities or specialized interests, they play a vital role in shaping public discourse and directing legislative attention towards critical matters that may otherwise be overlooked.
