Swadhin Bangla Betar Kendra (Bengali: স্বাধীন বাংলা বেতার কেন্দ্র, lit. 'Free Bengal Radio Centre') was the radio broadcasting centre of Bengali nationalist forces during the Bangladesh Liberation War in 1971. This station played a vital role in liberation struggle, broadcasting the Declaration of Independence and increasing mental state of Bangladeshis during the war. In 1971, radio was the only media reaching to the far ends of Bangladesh. It ran a propaganda campaign through the war.
The end of British rule in India in August 1947, accompanied by the Partition of India, gave birth to a new country named Pakistan which constituted Muslim-majority areas in the far east and far west of the Indian subcontinent. The Western zone was popularly (and for a period of time, also officially) termed West Pakistan and the Eastern zone (modern-day Bangladesh) was initially termed East Bengal and later, East Pakistan. The two zones were separated by over thousand miles of Indian territory in the middle, and had vastly different culture. It was widely perceived that the west zone dominated the country, leading to the effective marginalization of the east zone. Growing disenchantment among the people of East Pakistan finally led to civil disobedience followed by Bangladesh Liberation War in 1971.
During the period of Liberation War of Bangladesh, media supported mass sentiments. They aired patriotic songs and talk shows. In the process of achieving our independence by trouncing the atrocities of the Pakistani military forces, the war-time broadcasting station "Shadheen Bangla Betar Kendra" played a vital role- in increasing the mental state of the whole Bangali nation by informing us how well we are advancing towards the victory. Shadheen Bangla Betar Kendra reached its pinnacle during the liberation war being acclaimed as the stool pigeon of war news updates through ‘Chorom Potro’. In those days when radio was the only media reaching to the far ends of Bangladesh, Swadhin Bangla Betar Kendra eventually turned as the orator of the Bangladesh government in exile. It ran the nationalist campaign throughout the war in gearing up our freedom fighters moral and also mobilizing world opinion in favor of Bangladesh.
