 In this session, we are going to discuss the topic of revolution, that what is the definition, what's the concept, what are the main reasons, so it will be quite informative and interesting topic for the students of political sociology. A revolution is a fundamental and relatively sudden change. In every society, people expect that the process of change comes and then there is an adjustment. Because change is a permanent and important feature of any human society. Because as humans are human beings, they are not static, they all need change. But when we talk about revolution, so revolution is a sudden change. With that planning, there is no change in the process of change. In fact, revolution means that due to some reasons, there can be a sudden change. So in political power and political organization, which occurs when the population revolves against the government. Now, the common cause of revolution, which we see everywhere, that is the unsatisfaction of people with their government. That is, if people are not satisfied with their government, if they are not satisfied with the government, then they are suddenly up against their government. And then the opposition is filled so much that it seems to be a kind of revolt or rebellion. So typically, due to perceived opposition, that opposition can be political, social and economic. Or political incompetence. Sometimes the government's their performance in context of political issues, in context of social issues, and sometimes in context of their economic performance. That shows the incompetence of the government. So people, those were not satisfied with the performance of the government. They try to convince the government that there must be a change within the system. So broadly, revolutions denote fundamental objective and subjective changes institutionally and culturally in political arrangements and leaders, principles and orientations. Now, basically, what is the demand through revolution? Sometimes it is that institutional changes are made, cultural changes are made, in which context the political arrangements are changed. But many times it is that the change of leadership is required by the people. And many times it is that all the proper setup is required by the people. So the transformation of political fabric on which government is based. So, what does revolution mean? Revolution means change. Basically, what is the change? The political fabric, that is the political design, in a system that is controlling people, running people, running their political affairs. If people are not satisfied with it and they want to change it, then this change is done through revolution. So as past and present experiences have demonstrated, to say that revolutions are political struggles for great intensity. Now, here we have to keep in mind that sometimes people are involved in agitation. People protest against their own government. They have meetings. Sometimes there is a strike. But its purpose or meaning is not within the revolution. Because revolution means a complete change. And its basic instrument is through demonstration, through protest. But the intensity of protest should be very high. If it is high, then people will be successful in changing the system. But if there is no intensity in protest, if people don't do collective effort, then sometimes such preparations are done by themselves. The passage of time is over. And the purpose of the protest is not within the revolution.
