Bangladesh has seen two hundred years of colonization under the British Empire (up to 1947), and another twenty-four years' (up to 1971) rule under Pakistan. The period was marked by subjugation, oppression, economic disparity and suppression. The people had to struggle for freedom, which started with language, culture, and rights. The period of decolonization started in 1947 in undivided India, but the people of East Pakistan continued to struggle for rights. Ultimately, decolonization period was marked by the Language Movement in 1952 and this movement turned into a War of Liberation for the birth of a new nation in December 1971. As a revolutionary leader, Bangabandhu Sheikh Mujibur Rahman, the Father of the Nation, was the key to the birth of the country. The duration from 1948 to 1971 was a struggle for liberation fought by the common people with Sheikh Mujibur Rahman leading from the front. The book evaluates the indomitable leadership of Sheikh Mujibur Rahman. After covering Bangabandhu's lifespan of political struggle, the book evaluates the struggle and sacrifice of the Fathers of the Nation in their respective countries to free people from suppression and subjugation leading to freedom. Bangladesh was not a member of the United Nations (UN) and also not recognized by many countries until September 1974. The book discusses the role of Bangabandhu vis-à-vis the UN, which had its footprint in Bangladesh from March 1971. In a newborn country people worked all out, and Bangabandhu provided the leadership and created favourable conditions for UN relief operations that assisted building of Bangladesh.
