Anonymous began as an internet subculture in the early 2000s, particularly on platforms like 4chan. Initially, it was more about humor, pranks, and internet culture. The iconic Guy Fawkes mask, popularized by the movie V for Vendetta, became the symbol of Anonymous, representing rebellion against authority and the power of the collective.This chapter explores how an online group of pranksters morphed into a global movement capable of organizing protests, taking down websites, and challenging oppressive regimes. It also delves into key early events like Project Chanology, which targeted the Church of Scientology and was the first major protest under the Anonymous banner.
