What happened
Twenty-nine newly independent Asian and African states met in Bandung, Indonesia, from 18–24 April 1955. They adopted a unanimous 10-point declaration condemning colonialism in all its manifestations, affirmed principles of peaceful coexistence, and committed to mutual technical and economic cooperation.
How we know it
The record is the official conference documentation: the final communiqué, its annexes including the unanimous 10-point declaration, and contemporaneous diplomatic records cited in verified claims. These documents name the organisers, participants, dates, location, and outcomes.
Why it went that way
It went that way because five host nations — Indonesia, Burma, India, Ceylon, and Pakistan — coordinated deliberately to convene peers, not patrons; because delegates shared recent experience of formal independence; and because the agenda was narrowly focused on anti-colonialism and South–South cooperation, avoiding Cold War alignment.
What is still contested
Whether the consensus on colonialism represented genuine unity or tactical convergence; whether the ‘Bandung Spirit’ produced measurable cooperation beyond symbolism; and how far the conference shaped later non-aligned movement structures — none of these are established by the source material.
What it changed
It changed diplomatic language: for the first time, a bloc of formerly colonised states jointly defined colonialism as illegitimate in all forms — naming neither West nor Soviet exclusively but implicating both — and anchored sovereignty in mutual technical assistance, not aid dependency.
Is it worth your time
Yes — it is the first multilateral assertion of postcolonial agency on world affairs, codified in writing, with immediate diplomatic consequences and a durable rhetorical framework still invoked today.
