Raja Rammohan Roy (1772-1833), often called the father of Indian Renaissance and the maker of Modern India. Rammohan Roy believed in the modern scientific approach and principles of human dignity and social equality.
He put his faith in monotheism. He wrote Gift to Monotheists (1809) and translated into Bengali the Vedas and the five Upanishads to prove his conviction that ancient Hindu texts support monotheism. Raja Rammohan Roy founded the Brahmo Sabha in August 1828; it was later renamed Brahmo Samaj. Rammohan Roy did not want to establish a new religion. He only wanted to purify Hinduism of the evil practices which had
crept into it.

According to the terms of this alliance, Indian rulers were not allowed to have their independent armed forces.
They were to be protected by the Company but had to pay for the “subsidiary forces” that the Company was supposed to maintain for the purpose of this protection. If the Indian rulers failed to make the payment, then part of their territory was taken away as penalty.
For example, when Richard Wellesley was Governor-General (1798-1805), the Nawab of Awadh was forced to give over half of his territory to the Company in 1801, as he failed to pay for the “subsidiary forces”. Hyderabad was also forced to cede territories on similar grounds.

The Bakasht lands issue became a major ground of contention between the Bihar Provincial Kisan Sabha and the Congress Ministry.
The Congress Ministry had initiated legislation for the reduction of rent and the restoration of Bakasht lands. Bakasht lands were those which the occupancy tenants had lost to zamindars, mostly during the Depression years (1930s), by virtue of nonpayment of rent, and which they often continued to cultivate as share-croppers.
But the formula that was finally incorporated in the legislation on the basis of an agreement with the zamindars did not satisfy the radical leaders of the kisan Sabha.
The legislation gave a certain proportion of the lands back to the tenants on condition that they pay half the auction price of the land. Besides, certain categories of land had been exempted from the operation of the law.
