India

Weather

The Himalayas: huge natural walls in India. During the rainy season, there is low pressure over the mountains and that creates a sort of vacuum. It sucks all the wind, packed with moisture, from the Indian Ocean and rams it up against the Himalayas and dumps. All that moisture pours down the mountains and floods India. That, ladies and gentlemen, is the Wet Monsoon.

Eventually, the opposite happens where all the moisture leaves the Indian subcontinent and empties out. That gives us the Dry Monsoon.

Delhi Sultanate

The Muslims conquer India in a violent fashion and were able to take over the northern part of India. If people didn’t convert, then there were taxed. The Buddhists and Hindu temples were destroyed and looted. Under the Delhi Sultanate, they built really good centers of learning that are equivalent to modern day colleges. And they also had large scale irrigation works that a.) relieved some of the effects of the monsoons and b.) made other parts of India more suitable for farming.
