What so the difference  between pressure groups ,interest groups and movemnt groups ?? Explain me in detail by giving  examples

Organisations which try to influence the policies of the Government are known as interest groups. An interest group is formed when people belonging to the same occupation and with common interests come together to achieve a common objective. However, they may not directly control or share political power.

Movements, on the other hand, sought to influence governmental policies rather than directly participating in politics. Movements depend on mass participation of the people. 

Pressure groups exert pressure on the governemnt to listen to their demands by holding rallies and strikes.

·         They carry out campaigns and hold protests and rallies in order to gain attention and support of the people. They also try to influence media to pay attention to the issues raised by them.

·         Pressure groups organise protest rallies or disrupt government programmes.
