Manavedan Raja was born in the Kottakkal branch of the Zamorin Royal family of Calicut in 1855.
People, under the leadership of Gandhian K Kelappan, campaigned for the opening of Guruvayur Temple to all castes.
Mahatma Gandhi himself came to Kerala in support of the movement, and met with the Zamorin Manavedan Raja, who was the chief administrator of Guruvayoor temple.
Though the talks were not published, it is highly speculated that the Zamorin told Gandhi that he cannot take decisions which might cause great social unrest.
His fourth son, M. K. Vellodi joined Indian Civil Service and later became the first Chief Minister of Hyderabad State.
