A special-interest group is an organization that works towards the promotion of specific interests or causes. In the world of politics, these groups are commonly referred to as advocacy groups. However, there are many other terms that can be used to describe these types of organizations, such as pressure groups, interest groups, or lobby groups. Other terms commonly used include activist organizations, advocacy coalitions, and issue-based groups. These groups organize themselves around a particular issue or cause, such as environmental protection, civil rights, or consumer protection. Whatever term is used, special-interest groups play an important role in shaping public policy and advancing social causes.
