The East India Company was one of the most powerful and enduring organisations in history and had a long lasting impact on the Indian Subcontinent, with both positive and harmful effects. Although dissolved by the East India Stock Dividend Redemption Act 1873 following the rebellion of 1857, it stimulated the growth of the British Empire. Its professionally trained armies rose to dominate the sub-continent and were to become the armies of British India after 1857. It played a key role in introducing English as an official language in India. This also led to Macaulayism in the Indian subcontinent.
