‘Avant-Garde’ - Defined as the practice of implementing experimental or unusual ideas to human expressions such as fashion, art, lifestyle or culture. Avant-garde derives from the French language meaning 'advance guard'.
Applied to art forms as early as the mid 1800's, early pioneers of the avant garde were set on emphasising the social power of artists and branding them with equal status to that of the influential people of the time.
Famously Henri De Saint Simon wrote in 1825
'We artists will serve you as an avant-garde, the power of the arts is most immediate:
when we want to spread new ideas we inscribe them on marble or canvas. What a
magnificent destiny for the arts is that of exercising a positive power over society, a
true priestly function and of marching in the van [i.e. vanguard] of all the intellectual faculties!"
