When was the habeas corpus created?
Habeas corpus stems from English common law. The very first instance of its use is therefore likely lost to antiquity. Perhaps it would be better to ask when it became an important principle of law. The eminent legal scholar William Blackstone, in his "Commentaries on the Laws of England," attributed the act which secured habeas corpus for the English people to King Charles II. Charles II ruled England from 1660 to 1685, so it would be fair to say that habeas corpus became a true principle of English law during that period.
