This paper considers lessons from the past one hundred years of attempts to tax wealth in the UK. I start with the calls for a levy on capital made during and after the First World War, whose only supporter in Cabinet was Winston Churchill. I then discuss the perspective of major thinkers including John Maynard Keynes, Nicholas Kaldor, and the members of the Meade Committee, on the taxation of wealth. I also document various attempts at reform of taxes on estates and gifts, development gains, and owner-occupied property through the twentieth century. Finally, I reflect on lessons for the present day, drawn from these experiences.
