Britishers decided to introduce acts in the colonies as the colonies were part of the British Empire. Britain forced taxes on the English colonies because they needed wealth to get rid of war debts. To pay the debt British introduced different types of taxes, including the Stamp Act, Townsend Acts.
The Acts implement by the parliament in England as they only wanted to get rid of the debts, which led them in financial troubles. British crown decided to charge the colonists with high taxes to help the British in somewhat lessen the burden.
The colonist grew enraged by the taxes, that led them to act against the British rule. The colonists were not happy with it, which resulted in the War of Independence. Ultimately in the coming years, America fought a war and became victorious.
The greatest effect of the European intrusion into the Americas was to increase the Indian and mestizo population through intermarriage with the whites. The primary cause of the massive population decline among native Americans after the European arrival was not warfare but disease.
