The domains of academic inquiry, management of practical problems, and popular engagement with psychological ideas have each contributed to the establishment of psychology in England. The mid-nineteenth century saw the emergence of a set of conditions that allowed psychology as a separate discipline and practice to emerge. This chapter examines those conditions before considering the moves to institutionalisation of psychology in the early twentieth century. However, even by then psychology’s presence in England was precarious and it was not until the years between the two World Wars that it gained a more established position in universities, in places such as schools and factories, and in the popular imagination. The chapter examines how this was achieved and concludes with a brief review of the conditions immediately post-World War II that allowed for the large expansion of psychology in England that took place in the last third of the twentieth century.
