“If we don’t get it right, we don't get to come home,” Jason Momoa says of bringing Hawaiian history to life in his new show, Chief of War. He continues, “It has to be on point. There’s no doubt about it.”

From Ka‘iana to Kamehameha, here's a vital reference guide on all the key characters in the historical Hawaiian drama Chief of War.

As the series opens, the kingdoms of O'ahu, Maui, Kaua'i, and Hawai'i are trapped in a non-stop cycle of war.
