In American history, the Gilded Age refers to substantial growth in population in the United States and extravagant displays of wealth and excess of America's upper class during the post-Civil War and post-Reconstruction eras of the late 19th century until WWI. Corresponding roughly to La Belle Époque in Europe, the Gilded Age connotes a refined, elegant aesthetic of art. Both artists and patrons wanted to show an America that had matured beyond its early provincialism and could equal Europe's culture and grace. During the Gilded Age, the role of the interior decorator evolved aesthetically and commercially from the high style interiors of the 1870s to the artistic sophistication of the 1880s. No artist represents the style of the Gilded Age more so than Louis Comfort Tiffany and the pieces sold by Tiffany Studios.
