The DCEU Aquaman movie promises to be an epic tale of the hero's quest to unite the Seven Kingdoms of Atlantis, but what exactly does that mean? When frequent DCEU director Zack Snyder released a tweet in 2015 showing Jason Momoa as Aquaman for the first time along with the words "Unite the Seven," fans speculated the "Seven" referred to Aquaman's team of DC allies in the upcoming Justice League film. But they later learned it referred to the Seven Kingdoms of Atlantis featured in a standalone Aquaman film directed by Jason Wan.
Even if you've read every Aquaman book since the character first appeared in More Fun Comics #73 in 1941, odds are you don't know all of the Seven Kingdoms. Only three have been detailed in the comics; others were created solely for the movie. This list dives deep into the mythos and lore of Aquaman and his associated characters, including Mera, to uncover as much as possible about these Seven Kingdoms without spoiling the movie.
