Constitutional history teaching started at Oxford University in the second half of nineteenth century, especially thanks to bishop William Stubbs, whose authoritative works were the basic teaching material for a long time. For several decades after its inception, constitutional history was characterised as a main product of the whig interpretation of history. Modernism and the transformations of British society caused a rapid loss of its traditional importance after the Second World War. However, even if its teaching stopped towards the end of the last century, it still shows signs of vitality in terms of research.
