The Knights Templar have a long history in England, with their presence dating back to the early years of the Order. They played a significant role in medieval English history, notably during the creation of Magna Carta in June 1215. Aymeric de St Maur, Master of the English Templars, was instrumental in its production and sealing at Runnymede by King John. Another influential figure was Sir William Marshal, 1st Earl of Pembroke, who mediated peace between King John and the barons and collaborated with Archbishop Stephen Langton on preparing Magna Carta. Magna Carta is recognised as a declaration of rights and liberties for freeborn Englishmen and is considered the world's first "Bill of Rights." Of the original 1215 copies, only four remain: two are housed in the British Library, while Lincoln and Salisbury cathedrals hold one each. Both Aymeric de St Maur and Sir William Marshal were interred at London’s Temple Church. Effigies of Sir William, his son (also named William), and other knights can be seen there. Before his death, Sir William became a Templar. The Temple area served as headquarters for English Templars from 1160 until their suppression. Also significant to the Order is All Hallows-by-the-Tower church—the oldest church in London—where beneath its modern altar lies another made from stones brought back by Knights Templar from one of their Holy Land castles; it was Richard the Lionheart's altar. In 2010, after being established initially in 1960 as a non-exclusively Roman Catholic priory and elevated to Magistral Priory status in 2009, England's Grand Priory was fully restored. Today, it includes members from various denominations, such as Anglicanism through to the United Reformed Church—all united under Christ’s banner.
