  • In 1866 Dadabhai Naoroji founded the East India Association in London. Its object was to inform the British of the true state of affairs in India.

As Member of British Parliament he rendered admirable service to the cause of India and the people of Indian origin in South Africa. It was due to the efforts of Dadabhai and Bradlaugh that the British House of Commons passed a resolution recommending that the ICS examination be held simultaneously both in England and in India. The Resolution, however, could not become an Act. He was one of the founders of the Indian National Congress. Thrice he presided over the Sessions of the Congress in 1886, 1893 and 1906. His Presidentship of the Congress in 1906 was memorable in many ways. The partition of Bengal in 1905 had very sadly disillusioned the early nationalists. Their power and prestige were on the decline. They, therefore, persuaded Dadabhai to preside over the Calcutta Session of the Congress in 1906.

    The cyber-world is ultimately ungovernable. This is alarming as well as convenient, sometimes, convenient because alarming. Some Indian politicians use this to great advantage. When there is an obvious failure in governance during a crisis they deflect attention from their own incompetence towards the ungovernable. So, having failed to prevent nervous citizens from fleeing their cities of work by assuring them of proper protection, some national leaders are now busy trying to prove to one another and to panic prone Indians, that a mischievous neighbour has been using the Internet and social networking sites to spread dangerous rumours. And the Centre's automatic reaction is to start blocking these sites and begin elaborate and potentially endless negotiations with Google, Twitter and Facebook about access to information. If this is the official idea of prompt action at a time of crisis among communities, then Indians have more reason to fear their protectors than the nebulous mischief-makers of the Cyber-world. Wasting time gathering proof, blocking vaguely suspicious websites, hurling accusations across the border and worrying about bilateral relation, are ways of keeping busy with in essentials because one does not quite know what to do about the essentials of a difficult situation. Besides, only a fifth of the 245 websites blocked by the Centre mention the people of the North-East or the violence in Assam. And if a few morphed images and spurious texts can unsettle an entire nation, then there is something deeply wrong with the nation and with how it is being governed. This is what its leaders should be addressing immediately, rather than making a wrongheaded display of their powers of censorship. It is just as absurd and part of the same syndrome, to try to ban Twitter accounts that parody despatches from the Prime Minister's office. To describe such forms of humour and dissent as 'misrepresenting the PMO- as if Twitterat is would take these parodies for genuine despatches from the PMO- makes the PMO look more ridiculous than its parodists manage to. With the precedent for such action set recently by the Chief Minister of West Bengal, this is yet another proof that what Bengal thinks today India will think tomorrow.
