Lee Teng-hui (Chinese: 李登輝; 15 January 1923 – 30 July 2020) was a Taiwanese politician and economist who was the fourth president of the Republic of China (Taiwan) under the 1947 Constitution and chairman of the Kuomintang (KMT) from 1988 to 2000. He was the first president of the Republic of China to be born in Taiwan and the first to be directly elected. During his presidency, Lee oversaw the end of martial law and the full democratization of the ROC, advocated the Taiwanese localization movement, and led an ambitious foreign policy to gain allies around the world.
After leaving office, Lee was known for expressing many controversial political opinions that were not public during his presidency. Lee was also expelled from the KMT for his role in founding the pro-independence Taiwan Solidarity Union (TSU), which forms part of the Pan-Green Coalition alongside Taiwan's Democratic Progressive Party. Lee was considered the "spiritual leader" of the TSU, and recruited for the party in the past. Nicknamed “Mr. Democracy”, Lee was the president who initiated Taiwan's transition to the democratic era.
He is also known as Li Denghui.
Lee died of multiple organ failure and septic shock at Taipei Veterans General Hospital on 30 July 2020, aged 97. He had suffered from infections and cardiac problems since he was admitted to hospital in February.
A state funeral is being planned, while a memorial venue at the Taipei Guest House where people may pay respects to Lee will be opened to the public from 1 to 16 August 2020, after which Lee's body will be cremated and his remains interred at Wuzhi Mountain Military Cemetery. All national flags at government institutions will be placed at half-mast for three days.
Lee had the nickname "Mr. Democracy" and Taiwan's "Father of Democracy" for his actions to democratize Taiwan's government and his opposition to ruling Communists in mainland China.
