Why did Sanford Dole and other Hawaiian sugar planters want Hawaii to join the us

The first known settlers of the Hawaiian Islands were Polynesian voyagers who arrived sometime in the eighth century, and in the early 18th century the first American traders came to Hawaii to exploit the islands' sandalwood, which was much valued in China at the time. In the 1830s, the sugar industry was introduced to Hawaii and by the mid-19th century had become well established. American missionaries and planters brought about great changes in Hawaiian political, cultural, economic, and religious life, and in 1840 a constitutional monarchy was established, stripping the Hawaiian monarch of much of his authority. Four years later, Sanford B. Dole was born in Honolulu, Hawaii, to American parents.

Some US business leaders wanted Hawaii to be annexed to the United States because it would improve trade with pacific rim countries. Hawaii became a state on August 21, 1959.
