Hanapepe massacre occurs on Kauai, Hawaii.
The Hanapēpē Massacre (also called the Battle of Hanapēpē) occurred on September 9, 1924 when an interethnic dispute amongst Filipino strike organizers in Hanapēpē, Kaua'i resulted in a violent exchange between local police officers and Filipinos. The conflict began when two Ilocano youth, allegedly breaking the Filipino-led labor strike, were detained and harassed by a group of Visayans at the Hanapepe strike camp. When the local police were called to settle the dispute, they arrived with a group of heavily armed special deputies. Upon arrival, the officers issued warrants of arrest for the two detained Illocanos, causing the collection of Filipino strikers to rally in opposition. Despite previously ridiculing the two Ilocanos, the remaining Filipinos armed themselves and demanded the boys be released. A violent exchange ensued wherein sixteen Filipino laborers and four police officers were left dead.
