Pride is the downfall of humanity. It can be found everywhere, in every man. Even those who are humble are often, in the words of Benjamin Franklin, proud of their humility. But the unlikeliest of outcomes can emerge from the pride of a few men.
Way back in 1763, life was good in the American colonies. The people had formed militias, marched alongside their British brethren, and defeated the French. A new land was open for settlement and opportunities, and that was all thanks to their British domination. They were proud to be British subjects. They were happy.
Others were not so happy. Fighting wars is expensive, and the British government had dug themselves into a money hole. No matter, they thought. We'll just raise taxes. The colonists in America will surely be glad to help finance the war we fought and won for them.
And they were right. The American colonists would have been perfectly happy to comply and give them everything they asked for. But a simple, ordinary event turned into a world-changing one. Something that should have been easy and barely a mark on the history books turned into the revolution that would rock the world. What happened?
See, the colonists in America all saw themselves as normal British subjects with the rights of British subjects, just as if they were living in England. They had set up their own governments and legislatures akin to Parliament that were recognized by the crown as the only legitimate government for the colonies. After all, it was impossible because of the distance to ever have Parliament govern the colonies. And those governments were happy to do the crown's bidding just as Parliament was. All the king had to do was ask for a tax, and the governments would levy a tax. They had never denied a request for a tax before and they had no plans to change now.
However, a certain pride had overtaken many in England, especially in the government. The colonists in America weren't seen anymore as equals, but as second-class, inferior to the people and government in England, unable to govern themselves properly, and bound to obey the government of Great Britain in all things. They didn't see the colonists as deserving of the English rights protected by the Magna Charta and the Glorious Revolution and so valued by all British subjects. They were simply servants, akin to the people living in the Caribbean or India or any other British colony.
So the British government didn't ask the colonies to levy taxes to help pay for the war. They simply levied a tax themselves. The infamous Stamp Act of 1765 was this tax. And the colonists were furious. They were a people with a rich history of peaceful rebellion and restraint on government. They had certain prized rights that their ancestors had defied kings to ensure. They weren't going to take an incursion on their rights lightly. The colonists formed a congress made up of representatives from their legislatures that wrote up a petition politely telling the king that Parliament had no jurisdiction over them and could he please reign in the excesses and power grab of Parliament? Less politely, the colonists made the lives of Stamp Act collectors so miserable no one wanted the job, and Parliament was forced to repeal the Stamp Act.
The incident could have ended there. But pride reared its ugly head and set the course of history on a different path. While repealing the Stamp Act, the members of Parliament declared that they did indeed have all authority to do whatever they wanted to the colonists. They told the colonists that they were indeed represented in Parliament, but virtually. In the same way as children, women, criminals, and the mentally insane weren't competent enough to elect their own representatives, but still represented by the members of Parliament, so too were the colonists.
Naturally, the colonists didn't take such an insult well at all. They didn't appreciate suddenly becoming second-class citizens when they'd been equals to mainland British subjects for so long. So when the Townshend Acts were passed, they were completely ignored. And the path had been set. The British government would not budge in treating the colonists like the second-class citizens they believed them to be, and the colonists would not let themselves be abused without a fight. British pride and superiority had destroyed the amicable relationship of the British and the American colonists.
And the rest? Well, it's history.
