It is difficult to say what the “best” definition of politics is, as different people may have different ideas about what is most important or useful to focus on when defining the term. Here is a broad definition of politics that captures some of the key aspects of the concept:
Politics is the process of making decisions that affect a group of people, especially the ways in which power and resources are distributed and used within a society. It involves the competition and negotiation among different individuals and groups who have competing interests and ideas about how to govern and address common issues. Politics can take place at many different levels, from local communities to national governments and international organizations, and it can involve both formal institutions and informal networks of influence.
