Why do countries decide to have someone “rule” them and to organize themselves into governing bodies?

The term government describes the means by which a society organizes itself and allocates authority in order to accomplish collective goals and provide benefits that the society as a whole needs. Among the goals that governments around the world seek to accomplish are economic prosperity for the nation, secure national borders, and the safety and well-being of citizens. Governments also provide benefits for their citizens. The type of benefits provided differ according to the country and their specific type of governmental system, but governments commonly provide such things as education, health care, and an infrastructure for transportation. The term politics refers to the process of gaining and exercising control within a government for the purpose of setting and achieving particular goals, especially those related to the division of resources within a nation.
