Law is a system of rules decided by people in a place for the purpose of keeping peace and order, and protecting liberty and rights. It is enforced by the police, courts or government officials who are trained in how to follow the law.
The law covers all kinds of issues, from how you treat neighbours to what you can do with your land. There are also laws about how you can run a business or operate your bank account. Most countries have a group of politicians in a legislature, called a parliament or congress, who make laws for the whole society. The law also sets out the rules for people to follow when they are working together.
Some of the most important laws include criminal law, civil law and constitutional law. Criminal law deals with the important issue of how the government stops people from breaking laws and punishes those who do. Civil law covers things like settling disputes between people and giving compensation (repayment) when they are injured or have their property harmed. Constitutional law is about how the government is organised and the important rights it gives people.
Other important laws include air law, banking law, family law, tax law and medical jurisprudence. These are all about ensuring that people follow the right rules and are treated fairly. International law sets out the rules for how countries can act in areas like trade and the environment. These are rules that all the countries agree to abide by.
The legal profession is all about helping people with legal issues, including advising and representing them in court. It is an increasingly attractive career choice for young people today.
The development of the law has been influenced by many different factors. For example, utilitarian theories of the law were popularised by philosophers like Jeremy Bentham in the 18th century. He argued that the law should be based on what is best for most of the people. Later, Max Weber reshaped thinking about the role of the state. He argued that modern military, policing and bureaucratic power can influence citizens in ways that earlier writers like Locke or Montesquieu could not have foreseen. The law may also be shaped by moral and political ideas, whether they are avowed or unconscious, and the prejudices that judges share with their fellow citizens. This reflects the fact that the law is a social product, not simply an abstract idea that can be proved by logical reasoning.
