Government is a system that gives a group the right to make and enforce laws. There are different forms of government based on who holds power and the structure of rule. Modern governments have roles like security, order, justice, welfare, regulation, and education. The main forms discussed are democracy, monarchy, theocracy, and dictatorship. Democracy gives supreme power to citizens through representation or direct voting. A monarchy has rule by a hereditary monarch, while a theocracy bases law on religion. A dictatorship concentrates absolute power in one leader. Economic systems like capitalism, socialism, and communism are also discussed in how private ownership and government control of production differ.
