The answer doesn't matter really. Yes it was a document for the times. But principles surrounding limits on state power are still as pertinent today as they were 800 years ago.
The Magna Carta has become an icon of liberty, variously credited with establishing everything from parliament to the rule of law. It is such a fixture of popular political thought that it is still rhetorically powerful eight centuries later. The Abbott Government's proposed citizenship law changes have been widely condemned as a violation of its principles.This is strange for something so archaic. The Magna Carta consists of about 3000 words of 13th century legalese about inheritance, feudal payments, land tenure and customary rights, in Latin, reflecting the economic and political concerns of a world distant from our own.There's one simple reason that the Magna Carta became the document of individual rights and a check against power that it is today.If you want to understand the Magna Carta, you need to understand that it is about tax.
