Lloa is a group of Austronesianindigenous Formosan people living in the southern plain of Taiwan. They have lived through the Dutch colonization of Taiwan, as well as the Manchurian occupation during the Qing Dynasty. The city of Chi-Lloa was named after the people, but was changed to Chiayi after the failure of their resistance to Chinese occupation in the 16th century due to the Manchurian conquest of China. The resistance had caused the genocide of much of the population, though many of them, especially women, changed their identity and were forced to marry other people groups.
Lloa are generally classified together with the Hoanya and Arikun as a single group, which idea has been rejected by some scholars and the indigenous people themselves.
