Hanapepe massacre

The Hanapēpē Massacre (also called the Battle of Hanapēpē since both sides were armed) happened on September 9, 1924. Toward the end of a long-lasting strike of Filipino sugar workers on Kauaʻi, Hawaiʻi, local police shot dead nine strikers and fatally wounded seven, strikers shot and stabbed three sheriffs to death and fatally wounded one; a total of 20 people died. The massacre brought an end to armed protests in Hawaii.

By the 1920s, the sugarcane plantation owners in Hawaiʻi had become disillusioned with both Japanese and Filipino workers. They spent the next few years trying to get the U.S. Congress to relax the Chinese Exclusion Act so that they could bring in new Chinese workers. Congress prevented the importation of Chinese labor.

But organized labor in the 1920s' U.S. mainland supported the Congress in this action, so that for a while it looked as though militant unionism on the sugarcane plantations was dead. To oppose organized labor, the Hawaiian Territorial Legislature passed the Criminal Syndicalism Law of 1919, Anarchistic Publications law of 1921, and the Anti-Picketing Law of 1923.

These laws, with penalties of up to 10 years in prison, increased the discontent of the workers. The Filipinos, who were rapidly becoming the dominant plantation labor force, had deep-seated grievances: as the latest immigrants they were treated most poorly. Although the planters had claimed there was a labor shortage and they were actively recruiting workers from the Philippines, they wanted only illiterate workers and turned back any arrivals who could read or write, as many as one in six.

By 1922 Filipino labor activist Pablo Manlapit had organized a new Filipino Higher Wage Movement which numbered some 13,000 members. In April 1924, it called for a strike on the island of Kauaʻi, demanding $2 a day in wages and reduction of the workday to 8 hours. As they had previously, the plantation owners used armed forces, the National Guard, and strike breakers paid a higher wage than the strikers demanded. Again workers were turned out of their homes. Propaganda was distributed to whip up racism. Spying and infiltration of the strikers' ranks was acknowledged by Jack Butler, executive head of the Hawaiian Sugar Planters' Association.
