HBO’s series The Gilded Age takes a close look at the families of New York’s High Society in the late 1800s, in particular, the Russells of New York. Much like other popular, scandal-filled period dramas like Bridgerton or Downton Abbey, The Gilded Age takes a fictionalized look at the lives and happenings of the rich, prominent families of New York, combining fact and fiction. The series was created by English actor and screenwriter Julian Fellowes, who also created Downton Abbey. Fellowes began developing The Gilded Age, which he described as an “American Downton,” for NBC in 2016 before the series eventually landed on HBO in 2019.
