Discovery of the AIDS Virus Announced
On April 23, 1984, U.S. Health and Human Services Secretary Margaret Heckler announced that a National Cancer Institute team led by Dr. Robert Gallo had discovered HTLV-III as the cause of AIDS. This breakthrough ended a period of intense scientific urgency, allowing for the immediate development of blood supply screening and diagnostic testing to curb transfusion infections. Although early vaccine predictions proved premature and the announcement ignited a dispute with French researchers who had independently identified the virus as LAV, the discovery laid the essential groundwork for future antiretroviral treatments. The pathogen was later unified under the name HIV.
Inauguration of the Mujibnagar Government
Triggered by Pakistan's Operation Searchlight military crackdown in March 1971, the Mujibnagar Government provided constitutional legitimacy and central command to the Mukti Bahini liberation forces. Led by Acting President Syed Nazrul Islam and Prime Minister Tajuddin Ahmad (with Sheikh Mujibur Rahman as President in absentia), it projected democratic leadership that secured crucial international support, shifting the Bengali movement from a demand for civil rights to a full-scale war for independence.
