The landmark speech also energised the entire nation and prepared the people for the Liberation War in 1971.
UNESCO included the speech in the Memory of the World International Register, a list of world's important documentary heritage, in 2017.
The speech effectively declared the independence of Bangladesh. It constitutes a faithful documentation of how the failure of post-colonial nation-states to develop inclusive, democratic society alienates their population belonging to different ethnic, cultural, linguistic or religious groups.
The speech was extempore and there was no written script. However, the speech survived in the audio as well as AV versions.
