The Gilded Age was a time in American history when the economy grew at its fastest rate in history. This had wide-reaching cultural and social effects, including a broadening tier of self-made millionaires, the rapid growth of the working class and a burgeoning black middle class.
It is against this backdrop of rapid change that Julian Fellows, creator of Downton Abbey, sets his new drama. We sat down with the show's historical advisor, Dr Erica Dunbar to help us understand the opportunities, challenges and tensions of this time.
The Gilded Age is available in the UK on Sky Atlantic and streaming service NOW from 25 January. For US audiences, it is available on HBO from the same date.
