United States diplomatic cables leak
The United States diplomatic cables leak, widely known as Cablegate, began on Sunday, 28 November 2010 when WikiLeaks—a non-profit organization that publishes submissions from anonymous whistleblowers—began releasing classified cables that had been sent to the U.S. State Department by 274 of its consulates, embassies, and diplomatic missions around the world. Dated between December 1966 and February 2010, the cables contain diplomatic analysis from world leaders, and the diplomats' assessment of host countries and their officials. According to WikiLeaks, the 251,287 cables consist of 261,276,536 words, making Cablegate "the largest set of confidential documents ever to be released into the public domain."
The first document, the so-called Reykjavik 13 cable, was released by WikiLeaks on 18 February 2010, and was followed by the release of State Department profiles of Icelandic politicians a month later. Later that year, Julian Assange, WikiLeaks' editor-in-chief, reached an agreement with media partners in Europe and the United States to publish the rest of the cables in redacted form, removing the names of sources and others in vulnerable positions. On 28 November, the first 220 cables were published under this agreement by El País (Spain), Der Spiegel (Germany), Le Monde (France), The Guardian (United Kingdom) and The New York Times (United States). WikiLeaks had planned to release the rest over several months, and as of 11 January 2011, 2,017 had been published.
