Minarchists are libertarians who believe that society should have a state with very limited power. They believe that free markets are the most moral and efficient way of providing goods and services. They typically believe that the only things the state should provide are police and judges to make sure that people obey the laws, and a military to make sure that no one attacks the country. Some minarchists believe in having a small amount of taxation and limited provision of public goods such as international diplomacy and public parks.
