Wade–Giles () is a romanization system for Mandarin Chinese. It developed from a system produced by Thomas Francis Wade, during the mid-19th century, and was given completed form with Herbert A. Giles's Chinese–English Dictionary of 1892. The romanization systems in common use until the late 19th century were based on the Nanjing dialect, but Wade–Giles was based on the Beijing dialect and was the system of transcription familiar in the English-speaking world for most of the 20th century. Both of these kinds of transcription were used in postal romanizations (romanized place-names standardized for postal uses). In mainland China Wade–Giles has been mostly replaced by the Hanyu Pinyin romanization system, which was officially adopted in 1958, with exceptions for the romanized forms of some of the most commonly used names of locations and persons, and other proper nouns. The romanized name for most locations, persons and other proper nouns in Taiwan is based on the Wade–Giles derived romanized form, for example Kaohsiung, the Matsu Islands and Chiang Ching-kuo. History Wade–Giles was developed by Thomas Francis Wade, a scholar of Chinese and a British ambassador in China who was the first professor of Chinese at Cambridge University. Wade published in 1867 the first textbook on the Beijing dialect of Mandarin in English, Yü-yen Tzŭ-erh Chi (), which became the basis for the romanization system later known as Wade–Giles. The system, designed to transcribe Chinese terms for Chinese specialists, was further refined in 1892 by Herbert Allen Giles (in A Chinese–English Dictionary), a British diplomat in China and his son, Lionel Giles, a curator at the British Museum. Taiwan used Wade–Giles for decades as the de facto standard, co-existing with several official romanizations in succession, namely, Gwoyeu Romatzyh (1928), Mandarin Phonetic Symbols II (1986), and Tongyong Pinyin (2000). The Kuomintang party has previously promoted Pinyin with Ma Ying-jeou's successful presidential bid in 2008 and in a number of cities with Kuomintang elected mayors. However, the current Tsai Ing-wen administration and Democratic Progressive Party along with the majority of the people in Taiwan, both native and overseas, use spelling and transcribe their legal names in the Wade–Giles system, as well as the other aforementioned systems.
