Advocacy group
groups using advocacy in order to influence public opinion and policy

Advocacy groups, also known as lobby groups, interest groups, special interest groups, pressure groups, public associations, government relations firms, or lobbying firms and in some cases public affirms firms, use various forms of advocacy or lobbying to influence public opinion and ultimately public policy. They play an important role in the development of political and social systems.
Motives for action may be based on political, economic, religious, moral, commercial or common good-based positions. Groups use varied methods to try to achieve their aims, including lobbying, media campaigns, awareness raising publicity stunts, polls, research, and policy briefings. Some groups are supported or backed by powerful business or political interests and exert considerable influence on the political process, while others have few or no such resources.
Some have developed into important social, and political institutions or social movements. Some powerful advocacy groups have been accused of manipulating the democratic system for narrow commercial gain, and in some instances have been found guilty of corruption, fraud, bribery, influence peddling and other serious crimes. Some groups, generally the ones with less financial resources, may use direct action and civil disobedience, and in some cases are accused of being a threat to the social order or "domestic extremists". Research is beginning to explore how advocacy groups use social media to facilitate civic engagement, and collective action.

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Apr 27, 2026. The linked authority identifier is Q431603. The Library of Congress control number is sh85106541. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.

Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
