Why was there a conflict between England and the American colonies?

In modern times, England became the largest colonial country. America was among the colonial lands of the British. It should be noted that by the middle of the 18th century, American dissatisfaction with the British had sharply increased. This was due to the fact that more and more taxes and duties were introduced, which went to the English treasury. In addition, the local population had to support the army of the mother country. This led to the fact that slogans began to sound about obtaining complete freedom from the metropolises. An important step towards gaining freedom was the famous “Boston Tea Party”.
