How can art define a sense of national identity?

In the midst of Brexit and in an age of political upheaval in the UK and abroad, how are ideas about national identity portrayed through art? How can art and spaces for art can define national identity? What is the role of the wider art community in defining national identity? Our discussion begins post-Wall Street Crash with the government's Works Progress Administration (WPA) programme, which aimed to generate art that re-examined American culture and values and define a new national identity. Using this as a catalyst for our conversation, we refocus our discussion on the contemporary UK art world, looking at how artists today are responding to times of national crisis. What is the role of the art community in forming ideas around what it means to be British today?
