History
Intended to be called Wat Prachathipatai (วัดประชาธิปไตย: Temple of Democracy), the temple was the initiative of Prime minister Plaek Phibunsongkhram. The temple would be the first temple built by the state, after the introduction of democracy following the Siamese revolution of 1932. The temple would be built close the Constitution Defense Monument in Bang Khen District's Lak Si Circle, which was near the site of a battle between the government led by the Khana Ratsadon (People's Party) and royalists under Prince Boworadet in 1933. The temple is significant: "not only for the government to ideologically proclaim their victory over the conservative royalists, but also to symbolize the efforts by the People’s Party to shape the political landscape of the country."

In 1940, Thawan Thamrongnawasawat the Minister of Justice was made a special envoy and sent on a mission to British India. As result of this trip the minister received a piece of the Buddha's relic found at Dharmarajika Stupa, Taxila, modern day Pakistan. Thawan also brought back five branches of the Bodhi Tree (at the Mahabodhi Temple) and some soil samples from various sacred Buddhist sites. The government decided to enshrined all of these relics at the temple and the temple's name was changed to Wat Phra Si Mahathat (Temple of the Sacred relics). In 1941 the government raised the status of the temple to that of a first-class royal monastery and the name was altered to Wat Phra Si Mahathat Wora Maha Viharn.

The construction of the temple was completed on 24 June 1942, precisely on the tenth anniversary of the revolution.
