The British government brought following constitutional changes in India :

1. Regulating Act:  An Act was passed in 1773 A.D. to check the activities of English East India Company. It was known as the Regulating Act. According to this Act :

• The civil and military administration of the company came under the control of the British Parliament. The Parliament got control over its revenue too.
• The governor of Bengal was made the Governor-General of the British India. A council of members was appointed to help the Governor-General in discharging his duties.
• The Governor-General was empowered to control the two presidencies of Bombay and Madras.

2. Pitt’s India Act: Pitt’s India Act was passed to remove the defects of the Regulating Act. According to this :

• Political and commercial functions of the company were separated. The Board of Directors was now to look after the commercial activities of the company only.
• A Board of Control consisting of six members was formed through which the British government could fully control the affairs of the company in India.
• The council of the Governor-General was to have three members instead of four.
• The Governor-General in council got complete powers to direct and control Bombay and Madras presidencies.

3. The Charter Act, 1833:

• The company was restricted to do trade through Charter Act of 1833 so that it could completely concentrate on administration of the British India.
• Governor-General and his council were given the name the Governor-General and his Council of India.
• A legal member was included in council of Governor-General to make laws for the country. Right of making law was taken away from presidencies governments. In this way control of government was made very powerful.

4. The Charter Act 1853: Another Charter Act was passed in 1853 A.D. Legislative and Executive were separated through this Act. Now total of 12 members were there in legislative. Interference of central government in the affairs of company was increased. Now it was free to take rule of India in its hands at any moment.
