After World War II, Taiwan was placed under the administrative control of the Republic of China (ROC), and the ROC flag was adopted.
The current flag of Taiwan, officially the flag of the Republic of China, was first flown in 1928 when the Kuomintang (KMT) party, led by Chiang Kai-shek, defeated the Beiyang Government and unified China.
The flag of Taiwan features a blue sky with a white sun and a red field. The colors symbolize the core values and principles of the Republic of China: liberty, democracy, equality, and fraternity. The twelve rays of the sun symbolize guidance and the 12 traditional Chinese hours, emphasizing the continual pursuit of progress and justice.
