Silver Age is a term traditionally applied by Russian philologists to the last decade of 19th century and first two or three decades of the 20th century. It was an exceptionally creative period in the history of Russian poetry, on par with the Golden Age a century earlier. The term Silver Age was first suggested by philosopher Nikolai Berdyaev, but it only became customary to refer thus to this era in literature in the 1960s. In the Western world other terms, including Fin de siècle and Belle Époque, are somewhat more popular.
