Politics, in Harold D. Lasswell's classic definition, is fundamentally about "who gets what, when, and how," highlighting the struggle for power and resources within a society and the processes through which decisions are made about their distribution and allocation. It involves the exercise of power and influence to shape policies, make collective decisions, and resolve conflicts over competing interests and values. Politics operates at various levels, from interpersonal relationships and small groups to national and international arenas, and is a central aspect of social organisation and governance.
