The Harappans ate a wide range of animal products. Archaeologists have been able to reconstruct use of animals from finds of charred animal bones found at Harappan sites. These include those of cattle, sheep, goat, buffalo and pig.
Archaeologists have found evidence of a ploughed field at Kalibangan (Rajasthan). The field had two sets of furrows at right angles to each other, suggesting that two different crops were grown together.
Representations on seals and terracotta sculpture indicate that the bull was known, and oxen were used for ploughing.
Terracotta models of the plough have been found at sites in Cholistan and at Banawali (Haryana). Most Harappan sites are located in semi-aridlands, where irrigation was probably required for agriculture. Traces of canals, water reservoirs and wells have been found at the Harappan sites indicate that agriculture was practiced.

Silver was being used since Harappan times. Sixth century BCE was an era associated with early states, cities, the growing use of iron, the development of coinage, etc.
It also witnessed the growth of diverse systems of thought, including Buddhism and Jainism. Early Buddhist and Jaina texts mention, amongst other things, sixteen states known as mahajanapadas.
While most mahajanapadas were ruled by kings, some, known as ganas or sanghas, were oligarchies, where power was shared by a number of men, often collectively called rajas. Both Mahavira and the Buddha belonged to such ganas.
In some instances, as in the case of the Vajji sangha, the rajas probably controlled resources such as land collectively.

In a bid to rectify the defects of the Regulating Act of 1773, the British Parliament passed the Amending Act of 1781, also known as the Act of Settlement. The next important act was the Pitt’s India Act of 1784.
Features of the Act
1. It distinguished between the commercial and political functions of the Company.
2. It allowed the Court of Directors to manage the commercial affairs but created a new body called Board of Control to manage the political affairs. Thus, it established a system of double government.
3. It empowered the Board of Control to supervise and direct all operations of the civil and military government or revenues of the British possessions in India.
Thus, the act was significant for two reasons: first, the Company’s territories in India were for the first time called the ‘British possessions in India’; and second, the British Government was given the supreme control over Company’s affairs and its administration in India.
