General Ne Win's assumption of power on 2 March 1962, while not unexpected, was nonetheless a surprise to many. It was executed in secrecy, and apparently even the deputy commander of the armed forces, Brigadier General Aung Gyi, was not informed until the next morning, though he must have been expecting it as early as November 1961, when he raised the prospect with colleagues. Others in the army, including Brigadier General Tin Pe, had been urging Ne Win to halt what they saw as a drift towards the dissolution of the Union of Burma. U Nu's cooperation with the Shan and Kayah traditional leaders in the Federal Seminar, and growing discontent in other minority areas caused by Nu's constitutional amendment making Buddhism the state religion, were creating political forces which many in the army felt the increasingly fractious Union Party government could not resist. Kachin Christians, led by former students fired by zeal for “Kachin national culture”, resented the installation of Buddhism as the state religion and the Shan Sawbwa, in the name of Shan “national determination”, were beginning to organize armed opposition to the government. The possibility of the Union Party splitting, as the AFPFL had done in 1958, became ever more likely, especially after Nu, the only person holding the party together, announced he would not run for office again after the next elections due two years hence (Silverstein 1977, p. 66). Planning for the corp commenced on 24 February, and twenty-eight officers were instructed as to what to do when the order for the coup was given. However, the date remained unknown until Ne Win gave the order (Mya Han and Thein Hlaing 2001, pp. 164–65).

Nu who was held incommunicado at Mingaladon from the middle of the night, initially believed that his detention was engineered by junior officers and soon Ne Win would come to his rescue (Nu 1975, pp. 141– 44). He, like many others, had false expectations, believing the past would be a guide to the future.
