বাংলাদেশ কবে স্বাধীন হয় ?
Modern Bangladesh emerged as an independent nation in 1971 after breaking away and achieving independence from Pakistan in the Bangladesh Liberation War. The country's borders coincide with the major portion of the ancient and historic region of Bengal in the eastern part of the Indian subcontinent, where civilisation dates back over four millennia, to the Chalcolithic. The history of the region is closely intertwined with the history of Bengal and the broader history of the Indian subcontinent.
