Oxford. Oxford is a university city in Oxfordshire, England, with a population of 155,000. It is 56 miles northwest of London, 64 miles from Birmingham and 24 miles from Reading by road. The city is home to the University of Oxford, the oldest in the English-speaking world, and has buildings in every style of English architecture from late Anglo-Saxon. Oxford's industries include motor manufacturing, education, publishing, information technology and science. Oxford was first settled by the Anglo-Saxons and was initially known as Oxenaforda, meaning ford of the oxen, as referenced in Florence of Worcester's Chronicon ex chronicis. A river crossing for oxen began around AD 900. In the 10th century, Oxford became an important military frontier town between the kingdoms of Mercia and Wessex and was raided by Danes. In 1002, many Danes were killed in Oxford during the St. Brice's Day massacre ordered by Æthelred the Unready. The skeletons of more than thirty suspected victims were unearthed in 2008 during the course of building work at St John's College. The massacre' was a contributing factor to King Sweyn I of Denmark's invasion of England in 1003 and the sacking of Oxford by the Danes in 1004. Oxford was heavily damaged during the Norman Invasion of 1066. Following the conquest, the town was assigned to a governor, Robert D'Oyly, who ordered the construction of Oxford Castle to confirm Norman authority over the area. The castle has never been used for military purposes and its remains survive to this day. D'Oyly set up a monastic community in the castle consisting of a chapel and living quarters for monks. The community never grew large but it earned its place in history as one of Britain's oldest places of formal education. It was there that in 1139 Geoffrey of Monmouth wrote his History of the Kings of Britain, a compilation of Arthurian legends. Additionally, there is evidence of Jews living in the city as early as 1141, and during the 12th century the Jewish community is estimated to have numbered about 80-100. The city was besieged during The Anarchy in 1142. In 1191, a city charter stated in Latin. Be it known to all those present and future that we, the citizens of Oxford of the Commune of the City and of the Merchant Guild have given, and by this, our present charter, confirm the donation of the island of Midney with all those things pertaining to it, to the Church of St. Mary at Oseney and to the canons serving God in that place. Since, every year, at Michaelmas the said canons render half a mark of silver for their tenure at the time when we have ordered it as witnesses the legal deed of our ancestors which they made concerning the gift of this same island; and besides, because we have undertaken on our own part and on behalf of our heirs to guarantee the aforesaid island to the same canons wheresoever and against all men; they themselves, by this guarantee, will pay to us and our heirs each year at Easter another half mark which we have demanded; and we and our heirs faithfully will guarantee the aforesaid tenement to them for the service of the aforesaid mark annually for all matters and all services. We have made this concession and confirmation in the Common council of the City and we have confirmed it with our common seal. These are those who have made this concession and confirmation. Oxford's prestige was enhanced by its charter granted by King Henry II, granting its citizens the same privileges and exemptions as those enjoyed by the capital of the kingdom; and various important religious houses were founded in or near the city. Oxford's status as a liberty obtained from this period until the 19th century. A grandson of King John established Rewley Abbey for the Cistercian Order; and friars of various orders all had houses of varying importance at Oxford. Parliaments were often held in the city during the 13th century. The Provisions of Oxford were instigated by a group of barons led by Simon de Montfort; these documents are often regarded as England's first written constitution.
