American Renaissance
The American Renaissance was a period of American architecture and the arts from 1876 to 1917, characterized by renewed national self-confidence and a feeling that the United States was the heir to Greek democracy, Roman law, and Renaissance humanism. The era spans the period between the Centennial Exposition (celebrating the 100th anniversary of the signing of the Declaration of Independence) and the United States' entry into World War I.
French Renaissance
The French Renaissance traditionally extends from (roughly) the French invasion of Italy in 1494 during the reign of Charles VIII until the death of Henry IV in 1610. This chronology notwithstanding, certain artistic, technological or literary developments associated with the Renaissance arrived in France earlier (for example, by way of the Burgundy court or the Papal court in Avignon); however, the Black Death of the 14th century and the Hundred Years' War kept France economically and politically weak until the late 15th century.
