The most profound case of the colonies being involved in England's ongoing feud with France would be the French and Indian War (known as the Seven Years' War in Europe). The Thirteen colonies played a very substantial role in the fighting of this conflict which began in 1761. After an initial defeat in the earliest of battles, George Washington played an important role as a leader in the fight against France and her Native American allies. Colonial militia and soldiers were active in all of the important battles of this war. The English, especially William Pitt, worked to make the British and colonial effort seamless and treated the American leadership as equals. Despite their cooperation in this conflict, the War would also expose deep-seeded differences in how the English and colonists defined their relationship.
