Taiwanese people are the citizens and nationals of the Republic of China (ROC) and those who reside in an overseas diaspora from the entire Taiwan Area. The term also refers to natives or inhabitants of the island of Taiwan and its associated islands who may speak Sinitic languages or the indigenous Taiwanese languages as a mother tongue but share a common culture and national identity. After the retreat of the Republic of China government to Taiwan in 1949, the actual-controlled territories of the government were limited to the main island of Taiwan and Penghu, whose administration were transferred from Japan in 1945, along with a few outlying islands in Fuchien Province which include Kinmen and Matsu Islands.
