Tashi Namgyal (; Wylie: Bkra-shis
Namgyal was the 11th ruler of the Namgyal dynasty of Sikkim, succeeding his half brother Sidkeong Tulku Namgyal, who had ruled from February to December 1914 - when he died, suddenly, under mysterious circumstances. Born in Tibet and crowned by the 13th Dalai Lama, Thubten Gyatso, he was a strong advocate for closer links with India.
He was educated in St. Paul's School, Darjeeling. He has married in October 1967 to Kunzang Dechen, and they had 3 sons and 3 daughters. The eldest son died in a plane crash during World War Two. On his death he was succeeded as Chogyal by his second son Palden Thondup Namgyal.
During his reign, he was known for land reform and free elections. He also favoured closer links between Sikkim, India and Tibet. Many people attribute his death to Indian agents.
About a decade after his death, his son Palden Thondup Namgyal, the incumbent hereditary Chogyal, was formally deposed. Prime Minister Lendup Dorji appealed to India to change the status of Sikkim from protectorate to statehood. On 16 May 1975, Sikkim was officially made the 22nd state of India.
