Legacy
Pridi remains a controversial figure in Thai modern history. As one of the leaders of the 1932 pro-democracy coup, he has been viewed in many ways. The first declaration of the "revolution," which harshly attacked the king and his government, was written by Pridi himself. Nevertheless, Pridi held the position of regent when
Rama VIII ascended to the throne.
During the period of military rule, Pridi was portrayed as a communist as several of his books and articles showed sympathy for Marxist, socialist, and communist ideologies.
With obvious conflict between Pridi and the King Rama VIII, the young king's tragic death came to be blamed on Pridi. Pridi was accused of being the leader of a plot to assassinate the popular young monarch. This culminated in the military coup in 1947.
In his later years,
Seni Pramoj promoted the idea that he had saved Thailand from post-war British colonial rule that Pridi had been willing to accept. Nigel Brailey treats the Free Thai movement as largely a sham and casts doubt on Pridi's part, arguing "it appears questionable whether Pridi committed himself personally to the Allied cause much prior to August 1942, if even then," suggesting that "his eventual anti-Japanese stance was a consequence primarily of his hostility to Phibun."
Pridi wanted to remove Phibun from power, and the war offered an opportunity to do so. However, Pridi recognised well before the war that Thailand's alignment with the Axis powers would work to Phibun's advantage and enable him to strengthen his
dictatorship

. Even the Japanese recognised Pridi's hostility, which is why he was forced out of the cabinet in December 1941. It was the reason every knowledgeable person on the Allied side, from Seni Pramoj and Prince Suphasawat, a chief organiser of the movement in Great Britain, to former British ambassador
Josiah Crosby, anticipated that Pridi would emerge as the head of a domestic resistance movement.
One-time conservative monarchist
Sulak Sivaraksa has emerged as one of Pridi's most ardent champions. A prolific critic of the Thai status quo, Sulak, in addition to praising the achievements of the Free Thai in saving Thailand's sovereignty, has criticised Seni and his Democrat Party for alleged complicity in the military's return to power in 1947.
Sulak led efforts to rehabilitate Pridi which achieved significant results. Four Bangkok streets now are named for Pridi: three as Pridi Banomyong Road and one called Praditmanutham (his royally granted title) Road. His birthday, 11 May, is now celebrated as Pridi Banomyong Day. In 1997, the Thai government dedicated a park in eastern Bangkok to the Free Thai resistance movement. On 16 August 2003, a library-museum, built as a replica of Pridi's wartime residence, opened at the park.
