The Seven years' War was initially a war among the main European powers in 1746, especially, Prussia and its allies (among the, England) against Austria and its allies (among them, France) for the control of lands coveted by Prussia to strengthen its economic power. Since England and France were on opposing bands, their rivalry was also transplanted to America, where the British had its Thirteen American Colonies and France owned the colonies of Louisiana and Canada, and also to India, where both countries had trade outposts and military strongholds.
The war between France and Britain did not really attract the interest of the American colonists so that they wished to take a part in. At one point of the war, the British Army was so badly in need of manpower that they offered, with the permission of the British government, a tax exemption to all the able-bodied American colonists volunteering to join the Militia and support the English troops. As the British government changed of mind after the war and withdrew the tax exemption to the American war veterans, it set the path to the American Revolution.
Another effect of the war in the regions closer to the military actions, near the border with Canada, was the frequent raids and destruction of lives and property by the Native American tribes allied with the French.
