The Committee of Safety, formally the Citizen's Committee of Public Safety, was a 13-member group of the Annexation Club. The group was composed of mostly Hawaiian subjects of American descent and American citizens who were members of the Missionary Party, as well as some foreign residents in the Kingdom of Hawaiʻi. The group planned and carried out the overthrow of the Kingdom of Hawaiʻi on January 17, 1893. The goal of this group was to achieve annexation of Hawaiʻi by the United States. The new independent Republic of Hawaiʻi government was thwarted in this goal by the administration of President Grover Cleveland, and it was not until 1898 that the United States Congress approved a joint resolution of annexation creating the U.S. Territory of Hawaiʻi.

The Hawaiian Kingdom, also known as Kingdom of Hawaiʻi, was a sovereign state located in the Hawaiian Islands which existed from 1795 to 1893. It was established during the late 18th century when Hawaiian chief Kamehameha I, from the island of Hawaiʻi, conquered the islands of Oʻahu, Maui, Molokaʻi, and Lānaʻi, and unified them under one government. In 1810, the Hawaiian Islands were fully unified when the islands of Kauaʻi and Niʻihau voluntarily joined the Hawaiian Kingdom. Two major dynastic families ruled the kingdom, the House of Kamehameha and the House of Kalākaua.
