Jinnah was born to Mahomed ali Jinnah bhai. in, some believe, Wazir Mansion, Karachi District, of lower Sindh. This is disputed as old textbooks mention Jhirk as his place of birth. Sindh had earlier been conquered by the British and was subsequently grouped with other conquered territories for administrative reasons to form the Bombay Presidency of British India. Although his earliest school records state that he was born on October 20, 1875, Sarojini Naidu, the author of Jinnah’s first biography, gives the date as ”December 25, 1876”.
