Naoroji was born in Bombay in a Gujarati-speaking Parsi family, and educated at the Elphinstone Institute School. He was patronised by the Maharaja of Baroda, Sayajirao Gaekwad III, and started his public life as the Dewan (Minister) to the Maharaja in 1874. Being an Athornan (ordained priest), Naoroji founded the Rahnumae Mazdayasne Sabha (Guides on the Mazdayasne Path) on 1 August 1851 to restore the Zoroastrian religion to its original purity and simplicity. In 1854, he also founded a Gujarati fortnightly publication, the Rast Goftar (or The Truth Teller), to clarify Zoroastrian concepts and promote Parsi social reforms. In 1855, he was appointed Professor of Mathematics and Natural Philosophy at the Elphinstone College in Bombay, becoming the first Indian to hold such an academic position. He travelled to London in 1855 to become a partner in Cama & Co, opening a Liverpool location for the first Indian company to be established in Britain. Within three years, he had resigned on ethical grounds. In 1859, he established his own cotton trading company, Dadabhai Naoroji & Co. Later, he became professor of Gujarati at University College London.
