The true story behind the events in 300: Rise of an Empire, the sequel to Zack Snyder's 300

The action-filled movie 300 focused on Ancient Greece's epic battle of Thermopylae, in which King Leonidas led 300 Spartans into battle against Xerxes and his million-strong Persian forces. In the sequel, 300: Rise of an Empire, the action moves to the sea, covering 10 years starting with the Battle of Marathon and ending with naval engagement the Battle of Artemisium, which occurred the same day as Thermopylae.

Rise of an Empire tells the story of the real men and events depicted in the movie, focusing on the Athenian general Themistocles, one of the world's greatest warriors. He became warlord of Greece, built their navy and, by uniting Greece to defeat Xerxes' fleet, enabled what we call western civilization. Packed with vivid detail, clashes of arms and ships, blood, and glory, Rise of an Empire tells a story even bigger than the big screen could contain.
