The paragraph is below.

Explanation:

in the 1760s the American colonies suffered from very unfair treatment from their rules, the English. They not only demanded their top quality products and loyalty. But they laid more taxes, taxes that decreased the revenue each producer got from his or her work. This and many other acts from the English crown cornered the American coloners because once they manifested their opposition to these laws, the English punished them hard. Thus, coloners came to a resolution, they were going to fight for justice and they saw what their fight could bring to them. They suffered more violence and punishment than ever, so they united and hit back. Their actions damaged the English empire and they realized it was not more than an ancient effigy so they realized they stood a chance. However English played dirty and tried to boycott many times their planes by offering privileges to their leaders, some fell and some kept loyal to justice. In the end, the colonies' habitants managed to repeal the English attacks and they got their freedom, their justice, and their land.
