Osman Ali Sadagar

Sadagar was born into a Bengali Muslim family in the Bengal Presidency.[4]

In 1885, he migrated to Alitangani in Nowgong, Assam with the help of his uncle, Nazrul Ali. Ali was working in the steam ships that flowed through the rivers of Bengal and Assam at the time.[4] He participated in the Battle of Patharughat of 1894 where he got injured.[5]

In 1902, Sadagar founded a primary school in Alitangani, Nowgong. According to doctoral researcher Hafiz Ahmed,[6] the school was the second Assamese-medium institution from the Bengal-origin Muslim migrant community of Assam.[7] Sadagar was also a member of the Asam Sahitya Sabha,[8] partaking in its inaugural 1917 session where he donated 10 British Indian rupees (today equivalent to 130 American dollars) to it.[9]

He independently contested in the first Assam legislative elections in 1937, and was successfully elected as a member of the Assam Legislative Assembly from the Nagaon constituency. In the politics of Assam, Sadagar opposed both ethnic Assamese politician Muhammed Saadulah and the ethnic Bengali politician Abdul Hamid Khan Bhashani. He later left the All-India Muslim League entirely.[10] Under his leadership, five independent Muslim politicians represented themselves in the assembly, who all opposed the Muslim League's plans to integrate Assam into the Dominion of Pakistan.[11]

Sadagar died in Assam. His son, Abdul Shahid, was also a politician.[12] In 2019, false NRC claims were made against his descendants.[2] Among those that defended them was the Leader of the Opposition Debabrata Saikia.[13][14][15]
