With Regards to India the spread of Modern Ideas of Nationalism, Liberty, Democracy and Secularism (though the Indian interpretation of Secularism is quite different from European Secularism or separation of the Church and the State) was one of the catalyst for the Indian Independence movement.

During the early 19th century the education in India was based on Indian Languages like Sanskrit and Persian as medium of teaching. In 1835 an amendment to the Charter act of 1833 made English the Medium of Education. This was done primarily to help the English East India Company to get a regular supply of low level clerks and consolidate its hold on India (Lord Macaulay (the chief backer of English as a medium of Instruction said in his famous "Minute on Indian Education" said "We must at present do our best to form a class who may be interpreters between us and the millions whom we govern; a class of persons, Indian in blood and colour, but English in taste, in opinions, in morals, and in intellect.")

However these actions had one unintended consequence it lead to the spread of Modern Ideas in India. Enlightened with such ideas the Indian Nationalist understood the true nature of English Rule. Initially the English Educated Elite were supporters of the British Rule as they believed that with the help of the British various social evils that plagued India at that time could be eradicated (like the practice of Widow Burning/Sati or the Caste System) and even supported the British in the Revolt of 1857. However gradually these people understood the true (exploitative) nature of the British rule in India and became its chief opponents. Though the education system propagated submission to authority but with the help of English these students were exposed to Modern Liberal Ideas as well. A fact in support of this argument is that from its foundation til Independence the top brass of the Indian National Congress (the foremost organisation in the Indian Independence Struggle) was composed of English Educated Intellectuals such Dadabhai Naroji to Mahatma Gandhi and Nehru.

The British always propagated the idea that its rule in India was to civilize the people of India ("White Man's Burden") thus if it tried to stop the spread of Modern Ideas by heavy handed practices such as banning books it would not only cause an uproar from several sections in England but also would be a dent on the sheer Moral Basis on which the Empire thrived. However it is to be noted that the Government did try other means to suppress the spread of such ideas such as regulation of the Press. Now it is to be noted that Press in India at that time was used to not only convey news but views and ideas as well and despite majority of the people being illiterate these were conveyed to them. In every village there was a Library Club where an educated member of the village (usually the Postman or other Government official) used to read out the Newspaper to his fellow villagers the ideas and the views were then discussed and debated. The Government used several measures such as the Vernacular Press Act, 1878 or the trial of writers on the pretext of seditious writing Here is a case but these were met with vehement opposition from the Indian Nationalist and even these measures could not control the percolation of ideas to the masses.
