Wat Tyler, ? - 1381
The Peasants' Revolt, Wat Tyler's Rebellion, or the Great Rising of 1381 was one of a number of popular revolts in late medieval Europe and is a major event in the history of England. Tyler's Rebellion was not only the most extreme and widespread insurrection in English history but also the best-documented popular rebellion to have occurred during medieval times .
Evidence presented by John J. Robinson in his book, Born in Blood: The Lost Secrets of Freemasonry, shows that the secret organisation behind the revolt were the Knights Templar (or their descendants), who's order was officially dissolved 69 years previously by Pope Clement V. Furthermore Robinson shows that the underground Templar orgnisation in Scotland and England at that time became the Freemasons, which still exist today. 
The following passages are taken from Born in Blood: The Lost Secrets of Freemasonry:
For several years prior to the revolt a group of disgruntled priests of the lower clergy had traveled the towns, preaching against the riches and corruption of the church. During the months before the uprising secret meetings had been held throughout central England by men weaving a network of communication. After the revolt was put down; rebel leaders confessed to being agents of a Great Society, said to be based in London.
During the revolt there were concentrated and especially vicious attacks on the religious order of the Knights Hospitaller of St. John, now known as the Knights of' Malta. Not only did the rebels seek out their properties for vandalism and fire, but their prior was dragged from the Tower of London to have his head struck off and placed on London Bridge, to the delight of the cheering mob.
There was no question that the ferocity unleashed on the crusading Hospitallers had a purpose behind it. One captured rebel leader, when asked the reasons for the revolt, said, "First, and above all ... the destruction of the Hospitallers." What kind of secret society could have had that special hatred as one of its primary purposes? A desire for vengeance against the Hospitallers was easy to identify in the rival crusading order of the Knights of the Temple of Solomon in Jerusalem.
While destroying Hospitallier property the rebels protected property originally owned by the Templars. Rolls and records in what had been the principal church of the Knights Templar in England were removed from the building before being destroyed, avoiding any damage to the church itself.
Some dissidents run for the woods and hide, while others organize. In the case of the fugitive Knights Templar, the organization already existed. They possessed a rich tradition of secret operations that had been raised to the highest level through their association with the intricacies of Byzantine politics, the secret ritual of the Assassins, and the intrigues of the Muslim courts which they met alternately on the battlefield or at the conference table.
The only evidence suggests the existence of just one secret society in fourteenth century England, the society that was, or would become, the order of Free and Accepted Masons. One connection between the revolt and Freemasonry was the name or titIe of its leader. He occupied the center stage of English history for just eight days and nothing is known of him except that he was the supreme commander of the rebellion. He was called Walter the Tyler. Tyler is the title of the enforcement officer of the Masonic lodge. In Freemasonry the Tyler, who must be Master Mason, is the sentry, the sergeant-at-arms, and the officer who screens the credentials of visitors who seek entrance to the lodge. In remembrance of an earlier, more dangerous time, his post is just outside the door of the lodge room, where he stands with a drawn sword in his hand.
