Don't teach indian history by travelling the world. To teach indian history you need to travel india.
Don't go into the past. You will regret whatever you have read. But, if you want a sample read this. There are more than 3 lac Kashmiri Hindu refugees in India (Majority Hindu country) driven from Kashmir. The Britishers only came to India for money. They stayed away from barbaric acts like forceful conversions( There were already christians in India before the arrival of Europeans along the West Coast).
The arrival of Britishers was the best thing to have happened to Hindus. Under the Britishers, the Hindus again followed their religion without fear. Since Hinduism alone is tolerant, the Hindus progressed and the muslims have only gone back to medieval ages. They only talk about killing. Pakistan was created by some Ex-muslim rulers by threatening Civil war and since Hindus are stupid - they agreed to give away their land.
