How did Liliuokalani threaten the hopes of united States for annexing Hawaii?

Queen Liliʻuokalani did not threaten the hopes of the United States for annexing Hawaii. In 1893, the Hawaiian monarchy was overthrown and a provisional government was established with Sanford B. Dole as president. The provisional government negotiated a treaty of annexation with the United States, but it was not approved by the U.S. Senate.
