"The Crown" released a new trailer Monday that teases tension between Queen Elizabeth and Prince Philip.
The season also follows Princess Margaret (Vanessa Kirby) as she moves on from her ill-fated romance with Peter Townsend (Ben Miles).
The princess is shown with her eventual husband, photographer Antony Armstrong-Jones (Matthew Goode).
Rolling Stone reported Season 2 takes place from 1956 to 1963, a period of great change for the British monarchy.
"The Crown" is based on series creator Peter Morgan's film "The Queen" and play "The Audience."
Season 2 will premiere Dec. 8 on Netflix, with Olivia Colman to take over as Queen Elizabeth when Seasons 3 and 4 jump forward in time.
