Politics is the way that people living in groups make decisions. Politics is about making agreements between people so that they can live together in groups such as tribes, cities, or countries. In large groups, such as countries, some people may spend a lot of their time making such agreements. These people are called politicians. Politicians, and sometimes other people, may get together to form a government  . The study of politics in universities is called political science, political studies, or public administration.

In everyday life, the term "politics" refers to the way that countries are governed, and to the ways that governments make rules and laws. Politics can also be seen in other groups, such as in companies, clubs, schools, and churches.
