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.
Medieval renaissances
The term was first used by medievalists in the 19th century, by analogy with the historiographical concept of the 15th and 16th century Italian Renaissance. This was notable since it marked a break with the dominant historiography of the time, which saw the Middle Ages as a Dark Age. The term has always been a subject of debate and criticism, particularly on how widespread such renewal movements were and on the validity of comparing them with the Italian Renaissance.
