The Royal Family of Hawaii refers to the lineage of monarchs who ruled the Hawaiian Islands before their annexation by the United States in 1898. The most notable monarchs include King Kamehameha I, who unified the islands in 1810, and Queen Liliʻuokalani, the last reigning monarch, who sought to restore the power of the monarchy before her overthrow in 1893. The royal family played a significant role in Hawaiian history, culture, and governance. Their legacy is preserved through various historical sites, such as Iolani Palace, and cultural practices that continue to be celebrated by the people of Hawaii today.
