I'm not really well-versed in history, so I've forgotten specifics like dates and whatnot. However, I know the gist of it. Someone else will correct me on the stuff I leave out/am wrong about, I'm sure.
Okay, way back in the day in the 1700s what we now know as the United States of America was composed of 13 small colonies along the east coast, which were under the rule of England. Being that America was rich in natural resources England went to great lengths to import many of these goods -- metal, agriculture, etc. -- from America, and decided to shaft the colonies with most of the bill in the form of tariffs. (
Taxes) A lot of tariffs. On top of that, the English generally treated the colonists like second class citizens anyway. Eventually the colonists said "f%$# it, I've had it with this colony s%$#" and decided they wanted their independence. England, unsurprisingly, wanted to hold on to their rich little colonies. Thusly, this small disagreement in the governing of the colonies was settled in the way most advanced, civilized countries settle disagreements: by attempting to kill each other.
So England sent troops to "reinforce" the structure of English rule, and some Colonists banded together and fought a guerilla war against the English. The French decided to help the Colonists as well, if I remember correctly. Eventually, after a bunch of people died the English came to some realizations: 1) marching troops in line formation wearing uniforms that prevent their heads from turning is a great way to get them all killed by one Colonist with even the remotest ability to be stealthy, and 2) they were going to have to take out damn near 75% of the Colonists and a bunch of French troops if they wanted to keep their colonies as colonies. And thus, America won its independence, to which there was much rejoicing, and drinking, and discharging of firearms, since we all love our guns here in America.
Incidentally, a lot of the Amendments in the Bill of Rights are direct responses to the actions of the English during colonial times. The 2nd Amendment -- the Right to Bear Arms -- is a response to the English law dictating that no Colonist was allowed to possess firearms, and I believe the 4th Amendment -- whatever one has that line about "housing troops" -- prohibited the act of garrisoning troops: kicking people out of their homes and using them as housing and/or bunkers for soldiers. The English loved to do that during the Revolution.
Now, someone point out how many mistakes I made and win a prize.
P.S. Never fight a land war in Asia.
