How the colonists were able to defeat the greatest world power of their time?

After the French and indian war in 1763 the Britain's weren't happy because they accused the colonists to not have participated on the war as much as they needed to have. At the same time the colonists were shocked that the British had so much trouble with the war realizing they're weakness and they thought maybe being a separate country that wouldn't be ruled by the British government.

Colonists at that time gained military confidence and experience and saw need to colonial unity to overcome problems. The border were safer because there were no more French or Indians because they'd been defeated. That meant for the colonists that they would be less dependent on the British armed troops.

Because the British believed that the colonists didn't help enough they wanted them to pay for the war costs. They needed to use only British ships for imports and exports and they needed to export specific materials to britain as sugar, tobacco, indigo and fur. They also were only allowed to import only from britain or pay duty and foreign goods. They had to pay unjustified taxes the Stamp act, one had to purchase stamps to put on printed materials like wills, newspapers, etc. Britain also put new taxes on import of paper, grass, paint, and tea which was a very important tradition to the colonists.

The colonists also had restriction. In 1763 King george III declared that colonists could no longer settle west of Applaties mountains, and the law required colonists to provide british soldiers food and living quarters when requested. It meant that if a soldier in war came to your house you should be his host and give him a place to live and things to eat for as much time as he stays.

The colonists reaction took place in 1765. They had a stamp act congress, delegated from 9 colonies met in New York to create plans to stand up against the stamp act. The british parliament reduced taxes of tea afterward but the colonists still had to pay taxes. In response to that they had a Boston tea party where colonial merchants who had smuggled tea from Holland to avoid tea taxes now could not compete. But still the British government had the control and had specific rules that the colonies qualified as Intolerable acts.

In 1774 They had the first continental congress to present unified colonial resistance to intolerable Acts, delegates from 12 colonies met in Philadelphia. Agreed to expend boycott of British goods and some colonists began forming and training militias and storing military supplies.

Afterwards they gained their independence.
