Foreign (primarily American and European) land acquisition in Hawaii accelerated through a series of legal, economic, and political mechanisms in the 19th century:
King Kamehameha III, pressured by foreign advisors, divided land into three categories:
Foreigners could purchase Government Lands and, later, Crown Lands. The Māhele established private property (fee simple) — a Western concept alien to Hawaiian communal tenure.
Plantation companies (e.g., Castle & Cooke, Alexander & Baldwin — "Big Five") leased vast tracts from the monarchy and government for sugar/pineapple, effectively controlling land without full alienation.
Monarchy granted land to foreigners for "development" (e.g., Claus Spreckels — sugar; Henry J. Kaiser — development). Often controversial, seen as cronyism.
After the US-backed overthrow of Queen Liliʻuokalani, the Republic of Hawaii (1894–98) and then Territory (1898–1959) facilitated massive land transfers to US corporations and military (Pearl Harbor, Schofield, Makua). The 1895 Land Act opened former Crown/Government lands to homesteading — largely snapped up by speculators and plantations.
By 1920, ~80% of arable land was foreign-owned. The Hawaiian Homes Commission Act (1920) set aside 200,000 acres for native Hawaiians — a partial, flawed remedy.
