UNESCO Constitution Enters into Force
After the required acceptances, UNESCO's founding document acquires legal force.
On 4 November 1946, the UNESCO Constitution entered into force after the conditions for acceptance by member states had been fulfilled. This was a separate event from the adoption of the document in London on 16 November 1945.
With the Constitution in force, the international organisation received a formal legal basis for work in education, science, culture and the exchange of knowledge. It became part of the broader post-war system of international cooperation.
The founders argued that ignorance, prejudice and mutual distrust contributed to conflict, and that durable peace therefore required institutions supporting cultural and educational connections.
The distinction between adoption and entry into force is important for historical accuracy: the first is agreement on the text, the second marks the legal beginning of the founding document's operation.
