Final answer:
Hawaii's sovereignty ended with the overthrow of Queen Liliʻuokalani on January 17, 1893, and was formalized with the US annexation in 1898.
Step-by-step explanation:
The sovereignty of Hawaii came to an end when the monarchy was overthrown on January 17, 1893. The provisional government was established by a group of European and American businessmen with the backing of the United States military. The dissolution of sovereignty was solidified with the formal annexation of Hawaii by the United States in 1898. Although Hawaii's sovereignty was greatly undermined following the overthrow of Queen Liliʻuokalani and the establishment of the Republic of Hawai'i, it was the annexation that marked the definitive end of Hawaii as an independent nation.
