I was born a very conservative, religious Hindu. I will give you what I know:

1. No much of recorded wars because we were not good with writing history and recording events. For over the last thousand years, India was one of the most invaded countries in the world. That is the only time we kind of took breaks from our infighting. We were busy being ruled by invaders from Persia, Mughalistan, Afghanistan, Greece, Portugal, France, Holland, Britain and so on.

2. India had over 6,000 kingdoms and they were always busy fighting among themselves. When the invaders came, many of them joined hands with the invaders to preserve their kingdoms and lifestyles.

3. There is a peculiar attribute of Hindus. We do not fight the enemy. When the enemy comes, we either join hands or just surrender. That is why we were always conquered by smaller countries by size and population. However we were very good at infighting, harassing own women and children with most primitive traditions and dictates. The same behavior is on full display in India now with Hindu nationalists. These people will not join the army to fight the enemy but will do riots and beatings in streets.

4. There are a very few events of armed rebellions during foreign occupations. Smaller rebellions were squashed very quickly and brutally like Mir Amir Taimur from Mighlaistan killed a thousand people in Delhi in 2 hours in 1200s. The biggest rebellion that is known and talked about was against the British rule organized by Indian kings was in 1857. That was squashed too.

5. We are passive by behavior. We call ourselves peaceful but it is just another name for cowardice. It has been evident throughout the history.

6. Yes, we believe there are 330 million Gods and all live in the sacred cow - although Hindu meat eating and animal sacrifices are known throughout the ancient history. Today, India is the biggest exporter of beef to the world after Brazil.

7. Why we are so passive or coward. My guesses are 2. We were vegetarian and peaceful farmers in the Indus valley in the beginning. We were not explorers or fighters. We retreated each time there was an invasion. Secondly, we have misconstrued the meaning of being peaceful in the scriptures. We have taken it as - do not respond to aggression. Gandhi added to it with his quote - if you slap me on one cheek, I will offer another.

8. It is false that there are no or little meat eating in India. Meat consumption in India is heavy.

Aboriginals, from whatever area, are ignored, After all, to have worthwhile gods, you can't be one with nature, can you?

I think you have it backwards, Buddhism is more peaceful than Hinduism. I could be wrong about this, but at one point in time the Hindus did wage war against the Buddhists.

So wrong try bangladesh or ceylon. it's quite often the indigenous versus the new comer. pakistan and india have 700k soldiers facing off in kashmir as we speak they shell each other daily

Some day, I hope people will stop dragging Bhuddism into the category of religions.

Bhagavad-Gita. Vishnu persuades Prince Arjuna to go to war with his cousins IIRC.
As a side note, Australian Aboriginal religious practices stretch back at least 50K years (possibly 68K). They always seem to be forgotten.

Since India became independant from England in 1948, the Hindus of India have periodically had small border skirmishes with the Moslems of Pakistan.
