The British passed the Rowlatt Act in the year 1919. The Act curbed fundamental rights such as the freedom of expression and strengthened police powers. The Act was very repressive and therefore it enraged Indians. Prominent leaders of the freedom struggles such as Mahatma Gandhi, Mohammad Ali Jinnah, etc. felt that the government had no right to restrict the basic freedoms of people. They viewed the Act as devilish and tyrannical. Gandhiji decided to oppose this Act. He asked people of India to observe 6 April 1919 as a day of non-violent opposition to the Act, as a day of “humiliation and prayer’ and hartal. He organised Satyagraha Sabhas to launch the movement.

It was in the year 1739, Nadir Shar, the Shah of Iran and the founder of the Afsharid dynasty, invaded India. Before Nadir's invasion, India was not united as the states were fighting among each other. Nadir Shah took advantage of a weak Mughal Empire as the right opportunity to seize power and invade India. Nadir Shah advanced towards India in 1738. He captured the western frontiers of Mughal Empire such as Kabul, Ghazni, Lahore in 1739. The Mughal emperor, Muhammad Shah was defeated in the final battle and Delhi was captured by Nadir Shah and his forces. 
However, as soon as Nadir Shah ascended the throne of Delhi, riots sparked off in the streets of Delhi in which a number of Persian soldiers were killed. THis enraged Nadir Shah and he ordered a general massacre of Delhi, which was also known as the infamous “Qatal-e-am”. During this massacre, the citizens of Delhi were looted and raided. Many locations of Delhi like Dariba Kalan, Fatehpuri, Chandni Chowk, Hauz Kazi, Faiz Bazar, Lahori, Johri Bazar, Ajmeri and Kabuli gates, were soon covered with corpses of both Hindus and Muslims.

• People had to resign from their government jobs.
• People were asked to withdraw their children from government-controlled or aided schools and colleges.
• People had to boycott foreign goods and use only Indian-made goods.

The industrialisation of Britain had a close connection with the conquest and colonisation of India. In the late 18th century the Company was buying goods from India and exporting them to England and Europe; making profit through the sale.

After the Company got Adam’s report, it immediately took decision to improve the system of vernacular education.
The Company appointed a number of pandits, each in charge of looking after four to five schools. The task of the pandit was to visit the pathshalas and try to improve the standard of teaching.
New routine and rules were introduced. Teaching was now to be based on textbooks and learning was to be tested through a system of annual examination. students were asked to pay regular fee, attend regular classes, sit on fixed seats and obey the new rules of discipline.

Despite laws that aim to create equality, the caste system in India continues to have a strong impact on society. ... The system has led to the upper castes being privileged over the lower castes, which were often repressed by those higher up on the caste scale. British colonial rulers would have self-imposed themselves as Brahmin during this evolution of the Caste system. ... This is due to the fact that caste is an ancient feature of Indian culture and therefore caste is an aspect of the content which would be generalised by the British as Hinduism. The government should take immediate steps to stop the scourge of caste system by (a) constituting fast track courts for giving immediate justice to the victims; (b) accelerating the “skill development” program so that the disprivileged community can acquire alternate skills; and, lastly (c) scrap the reservation
