Set against the backdrop of Regency era London, the Bridgerton siblings - Anthony (Jonathan Bailey), Benedict, Colin, Daphne, Eloise, Francesca, Gregory and Hyacinth - navigate the London society in search of love, surrounded by friends and rivals alike. Each episode includes narration by actress Julie Andrews, who voices the anonymous and ever-scandalous newsletter columnist known as Lady Whistledown (Julie Andrews), who possesses knowledge of all the information in London, drawing everyone's interest, even Queen Charlotte (Golda Rosheuvel).
Unlike the series of novels, Bridgerton is set in an alternate history with a racially integrated London where people of color are members of the ton, some with titles granted by the sovereign. Creator Chris Van Dusen was inspired by historical debate over the 1940s African ancestry claims of Queen Charlotte "...to base the show in an alternative history in which Queen Charlotte's mixed race heritage was not only well-established but was transformative for Black people and other people of color in England." Van Dusen says the series is not "color-blind" because "that would imply that color and race were never considered, when color and race are part of the show."
