The symbol is a recognizable icon used by many people who identify or sympathize with anarchism. Despite the history of militaristic use, by the dawn of the 21st century the enclosed A has largely supplanted the traditional black flag as the most-used anarchist symbol. This monogram consists of the capital letter "A" surrounded by the capital letter "O". The letter "A" is derived from the first letter of "anarchy" or "anarchism" in most European languages and is the same in both Latin and Cyrillic scripts. The "O" stands for order. Together they stand for "society seeks order in anarchy" (French: la société cherche l'ordre dans l'anarchie), a phrase written by Pierre-Joseph Proudhon in his 1840 book What Is Property?
