KAMALEHUA: THE SHELTERING TREE tells the true story of Timoteo Haʻalilio, Royal Secretary and lifelong friend to King Kamehameha III. Set in the mid-nineteenth century, the opera reveals the little-known history of the Hawaiian Kingdom and its early struggles to maintain independence. The focus is Haʻalilio's 1842-45 mission to the United States, Great Britain, Belgium, and France to secure treaties recognizing Hawaiʻi as a sovereign nation with the goal of protecting the kingdom from annexation by foreigners.

The opera illustrates the sophistication and establishment of the Hawaiian government at the time, as well as the vigilance of Hawaiian leaders in dealing with the pressures and politics of the western world. While the story focuses on the unique culture, politics, and history of Hawaiʻi, its themes are universal.
