Government is the institution that administers an organized society. It is a political system characterized by a set of laws, policies and practices that dictate the authority to take certain actions. Government is normally composed of three distinct institutions: the legislative, executive and judicial branches. A distribution of distinct powers among these different branches is a characteristic feature of most governments. The underlying philosophy of government is often based on the idea that it should be limited to protect citizens’ freedoms and property from unchecked power, corruption and other dangers. A government’s constitution is its statement of governing principles and philosophy.
Some government activities are necessary, such as providing national security and public education. These activities are often known as public goods, because they are in the interest of all people and cannot be provided by private enterprise because they require large groups of people to organize, plan, and implement them. Public goods are in limited supply and must be carefully managed to prevent them from becoming unavailable.
Other government activities are not strictly necessary but are important, such as providing services like parks, roads and libraries that benefit all citizens regardless of their income. In order to provide these services, money must be collected by government agencies and distributed to the appropriate entities for implementation. Governments may also provide social insurance programs such as unemployment compensation and pensions for the elderly or disabled. They may also provide funding for science research and the advancement of knowledge.
A government’s legitimacy is the degree to which the people it governs accept and support its actions. This includes the right to vote, to have access to information about government operations, and to have their rights protected by the courts. In the United States, this is reflected in the Constitution’s guarantee of civil liberties and the separation of powers between the executive, legislative and judicial branches.
There are many different forms of government, from monarchies to totalitarian regimes to democratic systems that fall somewhere in the middle. Governments are also classified according to whether they are ruled by one person (autocracy), a small group of people (oligarchy or aristocracy), or by the people as a whole (democracy). Governments at different levels also vary in the way that they allocate funds for specific purposes. At the local level, this might include paying for schools and libraries, maintenance of roads and bridges, and wildlife management. At the state and federal levels, this might involve paying for defense, Social Security, Medicare, and veterans’ benefits. At the federal level, it might mean funding national parks and providing federal law enforcement. At each level, representatives elected by the citizens try to secure funding for things that are important to their constituents. Governments also interact with other countries in many ways, including by sending diplomats to meet and discuss important issues. This can help avoid war and promote trade and cultural or social exchanges. They also communicate with each other through international organizations such as the United Nations.
