These three amendments were passed toward the end and following the Civil War. They ended the practice of slavery releasing blacks throughout the South from enslavement. The 14th and 15th Amendments provided rights and Constitutional protect for blacks in addition to giving them the power to vote. However, Southern governments found ways around the amendments to prevent blacks from exercising their full rights.

The French and Indian War was the nine-year North American chapter of the Seven Years War. The conflict, the fourth such colonial war between the kingdoms of France and Great Britain, resulted in the British conquest of all of New France east of the Mississippi River, as well as Spanish Florida. The outcome was one of the most significant developments in the persistent Anglo-French Second Hundred Years' War. To compensate its ally, Spain, for its loss of Florida, France ceded its control of French Louisiana west of the Mississippi. France's colonial presence north of the Caribbean was reduced to the tiny islands of Saint Pierre and Miquelon.
