The Hawaii Big Five was the name given to a group of what started as sugarcane processing corporations that wielded considerable political power in the Territory of Hawaii during the early 20th century and leaned heavily toward the Hawaii Republican Party. The Big Five were... 1. * Castle & Cooke 2. * Alexander & Baldwin 3. * C. Brewer & Co. 4. * American Factors (now Amfac) 5. * Theo H. Davies & Co.. The extent of the power that the Big Five had was considered by some as equivalent to an oligarchy.
