Shaheed Dibosh
Martyrs day. This February 21st day commemorates the lives sacrificed to make Bengali one of the national languages when Bangladesh was part of Pakistan. The West Pakistani regime tried to force Urdu as the national language, a fact that was strongly contested by Bengalis. On that fateful day a procession by Bengalis was shot at by police resulting in the death of 4 martyrs. The nascent Bengali nationalism ultimately gave birth to the free nation of Bangladesh.
Following a proposal made by Bangladesh, UNESCO created February 21st as the International Mother Language Day in 1999.
Independence Day
March 26. The day Independence of Bangladesh was formally declared on the eve of a 9 month long war of Independence with Pakistan that led to the emergence of Bangladesh as a sovereign nation. After many years of exploitation, both politically and economically, the Bengali national sentiments led to the massive victory of Sheikh Mujibur Rahman and the Awami League in the Pakistan National Elections of 1970. The ruling oligarchs in the then West Pakistan balked at having to give up the reigns of power to East Pakistanis. They stalled the installation of the newly elected parliament, and on the dark night of March 25, 1971 embarked on a genocidal reign of terror aimed at extinguishing all signs of Bengali nationalism. In the face of this, the inevitable declaration of independence was proclaimed, and the fight was on for the people of Bangladesh to achieve independence, at a terrible price of 3 million people killed by the marauding armies of Pakistan.
Victory Day
Bijoy Dibosh. December 16. On this day, after the nine month long independence war with Pakistan, the occupying armed forces of Pakistan formally surrendered to the allied forces of Bangladesh and India.
