Why are the traditional Chinese characters used in Taiwan different from the traditional Chinese characters used in mainland China?

Taiwan uses the "national characters" that were unified and promulgated in the early years of the Republic of China. After the liberation of the mainland, simplified characters were implemented and the writing methods of some traditional Chinese characters were also changed.
