Lord Macaulay was a British historian, essayist, politician, and poet. He is best known for his History of England from the Accession of James II, which was published in 1848–1855. He was also a member of the British Parliament and served as the chairman of the First Law Commission of India from 1834 to 1837.

The First Law Commission was established in 1834 by the British East India Company to codify the laws of India. The commission was chaired by Lord Macaulay, who was assisted by a number of Indian and British lawyers. The commission’s work resulted in the enactment of the Indian Penal Code, the Indian Evidence Act, and the Code of Civil Procedure. These laws are still in force in India today.
