What are the strongest pieces of evidence Gandhi gives to support his claim?

The strongest pieces of evidence that Gandhi gives to support his claim for the independence of India were:

1. The Indian people had been impoverished by the British rule.

2. The British administration had exploited India, milking it dry by instituting an unbearable administrative and over-bearable military infrastructure, which did not allow India to develop.

3. Indians were made to be mere laborers when it came to the governance of India.  They were denied the opportunity to self-rule.

4. India was built on a spiritual foundation, which was gradually eroded by the British rule.

Explanation:

Gandhi (1869 - 1948), was a lawyer, politician, social activist, and writer who led the nationalist movement against the British rule of India.  He is internationally esteemed and best remembered for his nonviolent way of agitating for India's independence from Britain.
