Before the Hawaiian islands were unified under one kingdom in 1850, they were warring factions also fending off white invaders.

The 'Game of Thrones' alum co-created and stars in the sweeping, action-packed drama about the unification of Hawaii in the 18th and 19th centuries.

Co-creator Jason Momoa stars as the late 18th century warrior Ka'iana in a story set at the intersection of the Hawaiian island kingdoms and the arrival of European colonists.
