The Hawaiian sugar industry was a significant part of Hawaii's economy from the 19th century until the late 20th century. Sugarcane was introduced to the islands by early Polynesian settlers and later expanded by American planters. The industry thrived due to Hawaii's ideal climate and fertile soil, leading to the establishment of numerous sugar plantations. However, by the 1990s, the industry faced challenges such as rising production costs and competition from cheaper imports. As a result, most sugar plantations closed, marking the end of an era. Today, the legacy of the Hawaiian sugar industry remains in the form of cultural and historical influences on the islands.
