Yes, it was mostly about taxes, but there were other issues. For example, Americans were forced to 'quarter' British soldiers in their homes. That is, a soldier could just come and live in your home and you couldn't do anything about it. Basically, the revolutionaries were angry because they were not treated as equals by the English. These Americans had thought of themselves as English, and when they realized they had no rights they were upset. They wanted an equal voice in Parliament. They wanted a say in the laws that were passed to govern them. If they couldn't be equal, they wanted to be free. At least 1/3 of the colonists did not want to revolt. But the war went forward anyway. There was always an issue of 'traitors'...that is, people who saw themselves as English. Many of these so-called traitors helped the English and were hanged as a result :)) Many lost their property after the war because they had stayed loyal to England.
