Spanish missionaries arrived Taiwan in 1626 when Taiwan was part of Fujian Apostolic Vicariate. However, it did not take root there. In 1883, Taiwan became part of Xiamen Apostolic Vicariate. Taiwan Apostolic Prefecture established in 1913 and ran by Spanish Dominicans.
In 1950, Taiwan split into 3 Apostolic Prefecture which are Taipei, Kaohsiung and Taichung. Substantial Church growth began since then after many priests, nuns and missioners left mainland China, following Kuomintang (Nationalist Party) members who retreated to Taiwan when the Communists took over the mainland in 1949.
To the east of Taipei is the Pacific Ocean, while to the north and west the Taiwan Strait. With an area of 278 square kilometers, Taipei has 12 administrative districts, namely Songshan, Zhongzheng, Datong, Wanhua, Wenshan, Nangang, Neihu, Shilin, Beitou, Zhongshan, Da'an and Xinyi, with Da'an the most densely populated while Shilin and Beitou the least.
Mandarin Chinese is the official language of Taiwan. However, at least half the population prefer to speak Taiwanese at home, especially for those living the southern region. Taiwanese, or the "Minnan" dialect, originated from Fujian province of mainland China. Minnan means "south of the Min River." Many elderly people also understand Japanese as a result of the 1895-1945 occupation of Taiwan by Japan. Taiwan's 10 aboriginal tribes each have its own language. These languages bear no relation at all to Chinese, and are generally regarded as Malayo Polynesian in origin.
