During the reign of King Edward III six measures, later known as the Six Statutes, were passed between 1331 and 1369. They sought to clarify certain parts of the Charters. In particular the third statute, in 1354, redefined clause 29, with "free man" becoming "no man, of whatever estate or condition he may be", and introduced the phrase "due process of law" for "lawful judgement of his peers or the law of the land". Between the 13th and 15th centuries Magna Carta was reconfirmed 32 times according to Sir Edward Coke, and possibly as many as 45 times. Often the first item of parliamentary business was a public reading and reaffirmation of the Charter, and, as in the previous century, parliaments often exacted confirmation of it from the monarch. The Charter was confirmed in 1423 by King Henry VI. By the mid-15th century, Magna Carta ceased to occupy a central role in English political life, as monarchs reasserted authority and powers which had been challenged in the 100 years after Edward I's reign. The Great Charter remained a text for lawyers, particularly as a protector of property rights, and became more widely read than ever as printed versions circulated and levels of literacy increased..
