Answer:
The word Politics is derived from Greek word 'polis' which means city-states. So in ancient Greece whatever concern city states (polis) was Politics and in modern time whatever concern modern state is Politics. Most established definition of Politics is "the activity through which people make, preserve and amend the general rules under which they live."
Diversity and scarcity are the twin facts of the society. In such society people have different opinions, different needs, different preferences, different wants, different choices, different interests, etc. Hence conflicts are inevitable. On the other hand people are also aware about importance of cooperation. (As noted by Hannah Arendt's political power is 'acting in concert.'). By this view, Politics in a broader sense is 'conflict resolution'. But all conflicts can not be resolved. Hence we can define Politics as being 'in the search of conflict resolution'.
