Taiwanese nationalism () is a nationalist movement which asserts that the Taiwanese people are a distinct nation. Due to the complex political status of Taiwan, it is strongly linked to the Taiwan independence movement in seeking an identity separate from China. This involves the education of history, geography, and culture from a Taiwan-centric perspective, promoting native languages of Taiwan such as Taiwanese Hokkien, Hakka, and indigenous languages, as well as reforms in other aspects.
No one can confirm when the concept of localism has started. Some say when the first large wave of Han people emigrated from mainland China to Taiwan in the mid-16th century, they must have wanted to maintain some independence from the control of the ruling class in their original hometown. Others say that only when the Kingdom of Tungning, with its capital at Tainan, was built by the Zheng family in 1662, did this concept appear.
Most Chinese contemporary scholars of Mainland China believe the roots of the localist movement began during the Japanese rule (1895 to 1945), when groups organized to lobby the Imperial Japanese government for greater Taiwanese autonomy and home rule. After the Kuomintang (KMT) took over Taiwan, the Taiwan home-rule groups were decimated in the wake of the February 28 Incident of 1947. The KMT viewed Taiwan primarily as a base to retake mainland China and quickly tried to subdue potential political opposition on the island. The KMT did little to promote a unique Taiwanese identity; often newly immigrated Chinese or "mainlanders" as they were called, working in administrative positions, lived in neighborhoods where they were segregated from the Taiwanese. Others, especially poorer refugees, were shunned by the Hoklo Taiwanese and lived among aborigines instead. The mainlanders often learned Hokkien. However, since Mandarin was enforced as the official language of the Republic of China and Taiwanese was not allowed to be spoken in schools, the mainlanders who learned Taiwanese found their new language skills to diminish.
