Weather had a great impact on Indian trade seasons. Hurricanes and winds in the ocean made it impossible at some times of the year to sail through the ocean and especially to India. The trade was very dependent on the weather patterns. But, the countries had found out what times are safe to travel. The bad times to travel were deadly, ships get swept up and destroyed.
It is interesting that India never became the greatest it could have been. With its size and population, it had the looks of being extremely powerful. The lack of protection of India's land seriously hurt it and truly caused the fall of it's trade. The weather seasons also hurt it because it was not a major trader all-year-round.
Why do you think India never tried to become powerful, even when they had the chance?
