A political power group is a type of organization that seeks to influence the decisions of government. The term 'BLOC' is used to refer to a group of countries, political parties, or other organizations that cooperate and work together to achieve a common goal. Blocs are often formed in order to gain more influence in international affairs, such as trade negotiations or military alliances. In domestic politics, blocs can be formed to support a particular candidate or party, or to oppose certain policies.
