Hindu patriot. Editor of the World Federation. Unofficial envoy of Afghanistan.
Pratap gave up his property for educational purposes, and he established a technical college at Brindaban. In 1913 he took part in Gandhi's campaign in South Africa. He traveled around the world to create awareness about the situtation in Afghanistan and India. In 1925 he went on a mission to Tibet and met the Dalai Lama. He was primarily on an unofficial economic mission on behalf of Afghanistan, but he also wanted to expose the British brutalities in India. He called himself the servant of the powerless and weak.
Member of the Commission of the Permanent International Peace Bureau. Doctor.
Gandhi stated in his paper "Young India" (July 4, 1929) that "Raja Mahendra Pratap is a great patriot. For the sake of the country this nobleman has chosen exile as his lot. He has given up his splendid property...for educational purposes. Prem Mahavidyalaya...is his creation."
