Pyarimohan Acharya was a 19th-century historian, educationist, and public intellectual from Cuttack in the modern-day state of Odisha, India.
Pyarimohan wrote his history in response to an advertisement by the colonial government of the time looking for a textbook for use in schools.
While the book was accepted by the government, its publication caused a controversy and was consequently not inducted into the school syllabus.
Odisara Itihasa nevertheless acquired prominence as it was the first history textbook to be written by a native author.
Apart from writing he also established P.M Academy School in 1875 in cuttack.
