Explanation:

The Revolutionary War was about American independence from Britain. The Spanish and Indian War is not a major conflict with this - scale power - shift impact. The Treaty of Paris is an agreement, not a conflict. The Seven Years' War (1756 - 1763) had England (Great Britain) and Prussia as major powers on one side. Britain gained a vast colonial empire, including much of North America, and Prussia solidified its position as a major European power.

Answer:

the Seven Years' War
