Tajuddin Ahmad (Bengali: তাজউদ্দীন আহমদ; 23 July 1925 – 3 November 1975) was a Bangladeshi statesman and freedom fighter. He served as the first Prime Minister of Bangladesh and led the wartime provisional government during the Bangladesh Liberation War in 1971. Ahmad is regarded as one of the most influential and instrumental figures in the birth of Bangladesh, due to his leadership of the provisional government in 1971, in which he united the various political, military and cultural forces of Bengali nationalism.
A close confidante of Bangabandhu Sheikh Mujibur Rahman, Ahmad was the general secretary of the Awami League in the late 1960s and early 1970s. He coordinated the League's election campaign for the 1970 Pakistani general election, in which the League gained a historic parliamentary majority to form a government. Ahmad, along with Mujib and Dr. Kamal Hossain, led negotiations with President Yahya Khan and Zulfikar Ali Bhutto for the transfer of power to the elected National Assembly.
