Bridgerton season 3 will further explore characters' backstories from Queen Charlotte: A Bridgerton Story, according to showrunner Jess Brownell. The spin-off series, which premiered on Netflix in May 2023, followed the eponymous monarch during two timelines – one set during the present-day Bridgerton timeline in 1817 and the other set in 1761 as Charlotte meets and marries George III. Bridgerton season 3, which returns to Netflix in May 2024, will follow another member of the titular family, Colin, and his romance with Penelope.
