Karsandas Mulji (25 July 1832 – 28 August 1871) was a Gujarati language journalist, writer and social reformer from India. According to 1911 Encyclopædia Britannica his death occurred in 1875, which may be more likely as it is mentioned that he was appointed to administer a state in Kathiawar in 1874. Born to a family belonging to the Kapol Caste, a trading caste of western India, he was repudiated by his family because of his views on widow remarriage. He became a vernacular schoolmaster and started Satyaprakash, a weekly in Gujarati, in which he attacked what he perceived to be the immoralities of the Maharajas or hereditary high priests of the Pushtimarg Vaishnavism, to which the Bhatias belonged. In a libel suit, the Maharaj Libel Case, brought against him in the High Court at Bombay in 1862, he won a victory on the main issue.
