David Icke is an English author and conspiracy theorist who transitioned from a career in sports journalism and broadcasting to developing his unique worldview. After experiencing health issues and engaging with New Age philosophies, Icke began to publicly share his unconventional ideas. He gained notoriety in the early 1990s for claims of being a divine messenger and predicting global catastrophes, which led to public ridicule.

His extensive writing, often self-published since the mid-1990s, details a complex cosmology involving vibrational energy, infinite dimensions, and an inter-dimensional race of reptilian beings called Archons. Icke posits that these Archons, often manifesting as a hybrid human-reptilian elite known as the Babylonian Brotherhood or Illuminati, manipulate global events to maintain human fear and control. He asserts that many public figures are part of this group, working towards a global fascist state. Icke proposes that awareness and love are the keys to overcoming this Archontic influence. His work has faced significant criticism, with accusations of antisemitism due to his promotion of The Protocols of the Elders of Zion and theories about Jewish families, leading to bans from several countries, though Icke denies these accusations.

Born in Leicester, England, David Icke's early life was marked by financial hardship. He found an outlet in football, developing into a promising goalkeeper. After being signed by Coventry City as a youth, his playing career was cut short at age 21 due to rheumatoid arthritis. Despite the pain, he continued playing part-time for Hereford United while working in a travel agency. His football career concluded in 1973, after which he moved into journalism, starting at the Leicester Advertiser.

Icke progressed from local journalism to national broadcasting, working for BBC Radio Leicester and eventually becoming a sports presenter for BBC's Newsnight and Breakfast Time in the early 1980s. He also co-hosted the flagship sports program Grandstand. During the 1980s, seeking relief for his arthritis, Icke explored alternative medicine and New Age philosophies, which sparked his interest in Green politics. He briefly served as a national spokesperson for the Green Party. His broadcasting career with the BBC concluded in 1990 after he publicly opposed the Community Charge.

In 1990, Icke's spiritual journey intensified after meeting psychic Betty Shine, who told him he had a purpose and would receive messages from the spirit world. This led him to declare himself a 'Son of the Godhead' in 1991 and predict global disasters, which were met with public ridicule, particularly after an appearance on the BBC show Wogan. He began developing his theories of a New Age conspiracy, which he has detailed in numerous books. His endorsement of The Protocols of the Elders of Zion led to his publisher declining further works, prompting him to self-publish.

Icke's central thesis involves the universe as vibrational energy across infinite dimensions. He asserts that Earth is controlled by an inter-dimensional race of reptilian beings, referred to as Archons or Anunnaki. According to Icke, these Archons, through a genetically modified hybrid race of reptilian shape-shifters known as the Babylonian Brotherhood, Illuminati, or the 'elite,' manipulate global events to foster fear in humans. This fear, he claims, provides a negative energy source that the Archons feed upon. He identifies many public figures as members of this group, aiming to establish a global fascist state or 'New World Order' that suppresses freedom of speech. Icke believes that awakening to this 'truth' and embracing love is the way to counteract this influence.
