The term ‘pressure group’ was coined after the post World War II era to put pressure among the higher authorities that has the power to make decisions. These pressure groups do not take part either in the elections nor do they have any interest in seeking power of the political office, their aim is just focused on implementing their opinions onto the powerful authorities (Baggott, 1995). Most of the time these pressure groups compete against the other pressure groups to make their demands fulfilled but when their aims are common, they often work together to achieve the shared interest. These pressure groups have increased rapidly in the 20th century duet to the increase in population around the world, advancement in the technology due to which many groups have started to raise their voices in the social media networking, the society is becoming more diverse and the increase in the welfare state has given rise to the pressure or interest groups (Walter & Zürn, 2005).
The pressure groups are considered as a mouthpiece for the members operating the group, which are not elected through formal electoral processes nor are they a part of any political parties but however they sometimes assist the parties in achieving their goals. Their main function is to mobilize the public opinion and persuading the government through different means in adopting the policies outlined by these groups. They educate the general public about specific issues from which they are unaware and they represent the minorities who are unable to represent themselves (Key, 1978).
The other most common function of a pressure group is to develop and recommend laws and policies and to ensure that these laws are implemented. These groups make the democracy healthy by indicating different issues to the government that have been overlooked.
