AUGUSTA — The Kennebec Historical Society will present “Why did Mainers from the Kennebec Valley Conspire to Overthrow the queen of Hawaii?” at 6:30 p.m. Wednesday, March 16, at the Maine State Library, 230 State St.

Speaker Jon Olson will explain the motivation and circumstances of the Mainers’ interventions in the affairs of a sovereign country, the legal and political ramifications of that action, then and now, and the remedy sought by the contemporary Hawaiian sovereignty movement which is both strong and deep.

Olson was raised in Jefferson, attended Jefferson Village School, Lincoln Academy and Bates College, and earned a bachelor’s degree in philosophy. He taught at Bonny Eagle High School in West Buxton and then lived in Hawaii for the next 36 years.
