What war are you talking about ?
Answer:
I believe it's two, gunpowder and crossbow
Explanation:
The soonest realized crossbows were designed in the main thousand years BC, not later than the seventh century BC in old China, not later than the fourth century BC in Greece (as the gastraphetes).
Gunpowder was developed in China at some point during the main thousand years AD. The most punctual conceivable reference to gunpowder showed up in 142 AD during the Eastern Han administration when the chemist Wei Boyang, otherwise called the "father of speculative chemistry", expounded on a substance with black powder like properties.
Islam was started by Muhammed a member of the Quarish Tribe(arabic) from somewhere in the Arabian Peninsula(unsure where exactly, probably Mecca)
The direct causes of the American revolution include the following:
1. Colonists rights were restricted.
2. Colonists were not represented in parliament.
3. Colonists did not want England ruling from far away.
4. Colonists were frustrated with high taxation.
All these factors led to the war between the American colonists and the British. Great Britain put in place a lot of policies which did not favored the American colonists, this include the payment of tax which the American colonists violently rejected.
