Daniel Estulin (born in Vilnius, Lithuania, August 29, 1966) is an author and public speaker whose main interest is the Bilderberg Group, an annual invitation-only conference of the elites in the fields of business, finance, media, military and politics. He is known for his extensive works on this group, having written a book called "The True Story of the Bilderberg Group", as well as for his live seminars throughout the world, and has been quoted as saying that the Bilderberg Group's "main objective is creating a world government ruled by an elite group of people whose main objective is to control the natural resources of the planet".
In an interview with conspiracy theorist and radio host Alex Jones, Estulin described his background, which led him to his profession:
"I’m a Russian expatriate who was kicked out of the Soviet Union in 1980. My father was a dissident who fought for freedom of speech who was jailed, tortured by the KGB. Suffered two political deaths. When these people got tired of us they threw us out. We moved to Canada and 12 years ago I came to Spain. My grandfather was a colonel in the KGB and the counter-intelligence in the 1950s, so I am privileged somewhat to get a lot of the information from secret service which are our best sources of information. Not only the KGB people but the MI6 people, the CIA because most of the people who work for the secret service as you probably know are patriots and they love their country and they’re doing it for the good of the nation and they’re the first ones absolutely terrified of the plans of the Bilderbergers".
Estulin wrote The True Story of the Bilderberg Group (original title: La Verdadera Historia del Club Bilderberg), purportedly a report on the nature and meetings of the world’s most powerful people. According to Estulin's book, the secretive Bilderbergers have been making major political, economical and social decisions since their first gathering in 1954.
Commenting on an episode in this book, Bruce Ramsey wrote "The method here is to initiate the reader into a special group of in-the-know; of mixing facts with assertions so that the casual reader won’t tell them apart, and to draw lines between A and B, when A is the person you want to impeach and B is a known wickedness."
In December 2007, Estulin appeared on the Alex Jones Show, and claimed that he had "received information from sources inside the U.S. intelligence community which suggests that people from the highest levels of the U.S. government are considering an assassination attempt against Congressman Ron Paul because they are threatened by his burgeoning popularity" as a presidential candidate. Estulin has worked with American journalist, the late James "Big Jim" Tucker who had a similar interest in the activities of the Bilderberg Group.
On August 19, 2010, the Cuban state news agency Prensa Latina published the full text of a "reflection" by former President Fidel Castro which was devoted to quoting Estulin from Los secretos del club Bilderberg, on the topic of "The World Government."  The selected quotes from Estulin's book focused on material credited to Lyndon LaRouche and members of his movement.
