Fin de Siècle is a French phrase meaning ‘end of century’ and is applied specifically as a historical term to the end of the nineteenth century and even more specifically to decade of 1890s
Fin de Siècle is an umbrella term embracing symbolism, decadence and all related phenomena (e.g. art nouveau) which reached a peak in 1890s. Although almost synonymous with other terms such as the Eighteen-Nineties, the Mauve Decade, the Yellow Decade and the Naughty Nineties, the fin de siècle however expresses an apocalyptic sense of the end of a phase of civilisation. The real end of this era came not in 1900 but with First World War 1914.
