Our Independence Day

26 March reminds us of the historic day in 1971 when Bangladesh declared its independence. It signifies the commencement of our nine-month-long Liberation War and the ultimate victory against oppression. The day is celebrated annually to commemorate the heroic struggle and immense sacrifices made by the people to achieve a sovereign nation.

26 March is observed as Bangladesh's Independence Day because on this day in 1971, the Father of the Nation, Bangabandhu Sheikh Mujibur Rahman, declared the independence of Bangladesh. This declaration ignited the Liberation War against Pakistan, leading to nine months of intense conflict. The day serves as a solemn reminder of the immense sacrifices made by millions of martyrs and freedom fighters who laid down their lives for the country's sovereignty. It is a day of national pride, remembrance, and renewal of the commitment to uphold the values for which the nation was founded.
