For many years England did little to regulate the North American colonies beyond appointing a royal governor. Both the mother country and colonies profited and prospered from their relationship with each other, but the English government treated the colonies with immense ignorance and indifference.
By the early 18th century, the colonies had begun to expand westward. Eventually this brought them into conflict with French settlers who were moving south from Canada along the Ohio River. (France and England were bitter enemies throughout the 18th century.) In the 1750s these powers fought for supremacy in North America. It eventually spread to Europe and is known as the Seven Years' War, but in America the war is called the French and Indian War.
In 1763 England defeated France, and Canada became an English possession. The war was paid for with English taxes and was won largely with English troops and ships so the English government had large debts from the war. England decided that the increasingly prosperous colonies should share in the cost of the war and began to enforce old laws more strictly and to pass new laws to raise colonial taxes. The colonists opposed every effort to make them pay more taxes and they believed that only their colonial assemblies could levy taxes and that Parliament had no right to tax them because the colonists did not vote for its members. (Taxation without representation.)
England put a tax on newspapers and then on sugar, tea, and other imported goods. Colonist boycotted goods then the Boston Tea Party happened which led to the Intolerable Acts.
All of which led to the American Revolution in which the American colonists formed an alliance with France, etc.
The Navigation Acts were originally designed to exclude the Dutch from any profits made by English trade, but they were one of the growing resentments the American colonists had against the mother country that fueled the flames of the American revolution.
So.....now that you have background let me sum this long-winded answer up! lol
The conditions were that England fought the war for/with the colonists when they collided with French settlers. Then they wanted colonists to pay their war debts through taxes.
I hope that helps and that you ace your paper George!
