The Magna Carta ("The Great Charter") is a fascinating constitutional document. You can find out more about it at the British Library website. Many view the Magna Carta as the cornerstone of common law legal systems and modern political constitutions.
To celebrate the 800th anniversary of Magna Carta, the International Review of Law and Economics has published a special issue on the topic. This special issue attempts to answer the following questions: What did Magna Carta actually say? What economic problems was it solving? Is it a constitutional document or a myth? Why did it endure over eight centuries? What has been its influence? Is it relevant today?
