Hawaii was one of the few locations free from imperialism, and was ruled under King Kalakaua. Due to this, New England missionaries went to Hawaii to spread their faith.
You're the problem!
The US government offered a deal to Hawaii called the sugar trade. Hawaii gave their sugar to the United States in exchange for generous terms. Profits grew after the civil war. The Bayonet Constitution was also signed around this time.
OVERTHROW THE QUEEN!
Later, congress approved of the William McKinley Tariff, who raised import rates on foreign sugar.The sugar industry in Hawaii crashed and depression came upon the sugar growers,
The sugar growers found that if Hawaii were to be annexed by the US, the problem would go away. At the same time of this idea, the throne was acquired by Queen Liliuokalani, who thought the problem was caused by immigrants, AKA the sugar growers.
The sugar growers in Hawaii staged an uprising to overthrow their queen. U.S. Marines went to the islands to interfere, and the queen was forced to renounce her throne. President Grover Cleveland, an anti imperialist, was disappointed in the Marines.
Cleveland withdrew the annexation, and aimed to give Liliuokalani her throne back. American public statement did not like this idea. Eventually Cleveland left office, and Hawaii remained a territory until granted fiftieth state.
