The College was founded in about 1263 (leading some to argue that it is the University's oldest college, a claim contested by University College and Merton College) by John I de Balliol under the guidance of the Bishop of Durham. After his death in 1268, his widow, Dervorguilla of Galloway (their son and grandson both became Kings of Scotland) made arrangements to ensure the permanence of the college in that she provided capital and in 1282 formulated the college statutes, documents that survive to this day.Along with many of the ancient colleges, Balliol has evolved its own traditions and customs over the centuries, many of which occupy a regular calendar slot.For many years, there has been a traditional and fierce rivalry shown between the students of Balliol and those of its immediate neighbour to the east, Trinity College. It has manifested itself on the sports field and the river; in the form of songs (of greater or less offensiveness) sung over the dividing walls; and in the form of "raids" on the other college. The rivalry poetically reflects that which also exists between Trinity College, Cambridge and Balliol's Sister College, St John's College, Cambridge.
