 When we want to evaluate the role of political parties and participation, specifically in context of building political behavior in developing and developed world, then definitely we have to evaluate that the first example we can take from the American political science that in American politics and American experts of political science, they explore that there are various important variables like that how the people try to vote, what voting choices are available, political engagements, partisan training, anti-influence of partisan elites. And those people who do political education, those people who mobilize people to take part in political events, what factors play a role in their education, we want to understand that in many cases no other single variable comes close to accountable as well as consistently for American political behavior. As a matter of fact, because there are a lot of political sociologists, there was a lot of diversity, there were a lot of ethnic groups, there were a lot of migrants who came and settled, so when you have to understand political behavior on all those people or those factors, how does political participation increase, how do people become a part of political action, but since empirical data was easily available, so the political sociologists, they made the American society the base, and there are a lot of topics, and that formula when they applied it in the developing world, then there are a lot of different things, that formula was not applicable, but the results of the results were possible. Because partisanship remains a potent political force, nonetheless if the influence of partisanship on political behavior is not in dispute, there remains a lively debate on its nature, origin and measurement, because four aspects are important, through which we can understand the political behavior, like through the lens of social identity theory. to generate strong emotion and drive political engagement, that is, first of all, it is necessary to see how the political community is doing, who is educating them, then what is its social nature, that is, people think in terms of how they think that they have to be a part of political action, and why they have to be, and especially if they become a part of political action, then their social identities, that is, if there is a special ethnic group, a religious community, a religious group, what class is it related to, that is, there are a lot of factors, when a person draws his political affiliation in the context of these factors, then what is the reason or logic behind it, this is the basic crux of this topic. The application of social identity theory in each of these areas have advanced the study of partisanship, if the influence of partisanship on political behavior is not in dispute, these remain a lively debate on its nature, origin, and environment. If social identity theory comes at risk, then what will be the decision? What will be the preference? How will it play its role in political action? Then definitely there are various origins in convergent identities and its ability to generate strong emotions and drive political engagements. Now we also have to understand that when men and women are together, then for them only their identity is important, but there are some other forces with which they become active, especially convergent identities, that is, if we see that if a particular group, if they are becoming a shareholder in some activities with another group, then there is no harm done to them, in fact, they are defending each other in a better way, then this will become a forceful factor, that convergent identities, if they are given more shares in political action, then they play a role as an important element, and then political engagements will become more. Then the application of social identity theory in each of these areas has advanced the study of partisanship. Now let's see that the concept of political partisanship is basically a very important role in this, that wherever there is a role of social identity theory, where people matter for their partisanship, sometimes they want to be a part of political action for their partisanship, sometimes they want to try to keep their partisanship together with other groups, but their fundamental point of view, the common concern in people is that they should not harm their partisanship, as much as there is political participation, as much as there is political participation, it is important for everyone that the people should not harm their partisanship, rather, they should be able to protect their partisanship from various aspects.
