Q4 pl answer

4. In 1803, the British gained control over Delhi by defeating the Maratha rulers.

In the first half of the nineteenth century in Delhi, the British lived with wealthy Indians in the Walled City.
 The Delhi College was set up in 1792. This led to the development of  great intellectuals in science and humanity. The period from 1830 to 1857 was referred to as the period of Delhi Renaissance.After the revolt of 1857, everything changed. The British wanted the people of Delhi to forget about their Mughal past.

 The British got rid of the gardens, mosques and pavilions which surrounded the Fort. One-third of the city was demolished and the canals were filled up.It took 20 years for building the city of New Delhi. The main idea was to build a city that was in stark contrast to Shahjahanabad. In contrast to the chaos of the Old Delhi, the architects wanted New Delhi to represent a sense of law and order. It had to be clean and hygienic and free from diseases.
