Here you consider constitutions as they apply to states. Other organisations such as sports clubs, companies, local authorities, Police Scotland, charities, volunteering organisations, the United Nations and Council of Europe also have constitutions which share some of the features of state constitutions. These are often contained in the form of rules, memorandum or articles of association.
Most state constitutions develop over time and evolve as the structures of society in which they exist develop. Some constitutions are created as a result of conflict or rebellion (which generally results in a single constitutional document). For example, the French constitution was redrafted in the period leading to the declaration of a republic in 1792, and has been redrafted or refined on a number of occasions since. The Constitution of the United States of America developed after war with England. It first came into effect in 1789 and has been amended 27 times since.
