Why did the planters stage a revolt in Hawaii?
To build upon that, in 1890, the McKinley Tariff had been implemented upon the planters which raised taxes on Hawaiian products. The planters revolted against the tariff, and discovered that the only way to overcome the tax would be to have Hawaii annexed to the union. Therefore, the planters were fighting the tax, in addition to fighting for the annexation of Hawaii in order to avoid the tax.
