Historical Trajectory
Phase I: Rise
Burma gained independence from Britain on 4 January 1948 under Prime Minister U Nu, inheriting a fractured post-war society. Almost immediately, the new state faced armed uprisings from the Communist Party of Burma (white flags), the Red Flag Communists, the People's Volunteer Organisation, and the Karen National Union, leaving the government controlling little territory beyond Rangoon in its earliest years.
Phase II: Zenith
Despite persistent insurgencies, the parliamentary government achieved periods of relative stability and pursued a non-aligned foreign policy during the Cold War. Burma became a founding member of the Non-Aligned Movement, maintained diplomatic relations with both East and West, and attempted land reform and nationalization programs. Rangoon functioned as a regional diplomatic hub, hosting international conferences through the 1950s.
Phase III: Decline
By the late 1950s political fragmentation within the ruling Anti-Fascist People's Freedom League and the ongoing multi-front insurgencies weakened civilian authority. General Ne Win staged a caretaker administration in 1958 before elections briefly restored U Nu. On 2 March 1962, Ne Win launched a full military coup, arresting elected leaders and dissolving parliament, ending Burma's first democratic era.
