For Dummies is an extensive series of instructional / reference books which are intended to present non-intimidating guides for readers new to the various topics covered. Despite the title, their publisher has taken great pains to emphasize that the For Dummies books are not literally for dummies. The subtitle for every book is, "A Reference for the Rest of Us!". To date, over 1,600 For Dummies titles have been published. The series has been a worldwide success with editions in numerous other languages.

The books are an example of a media franchise, consistently sporting a distinctive cover—usually yellow and black with a triangular-headed cartoon figure known as the "Dummies Man", and an informal, blackboard-style logo. Prose is simple and direct; bold icons, such as a piece of string tied around an index finger, are placed in the margin to indicate particularly important passages.

Almost all Dummies books are organized around sections called "parts", which are groups of related chapters. Parts are almost always preceded by a Rich Tennant comic that refers to some part of the subject under discussion. Sometimes the same Tennant drawing reappears in another Dummies book with a new caption.

The Korean War (Korean: 한국전쟁 or 조선전쟁, Hanja: 韓國戰爭 or 朝鮮戰爭; 25 June 1950 – 27 July 1953) was a war between the Republic of Korea (supported primarily by the United States of America, with contributions from allied nations under the aegis of the United Nations) and the Democratic People's Republic of Korea (supported by the People's Republic of China, with military and material aid from the Union of Soviet Socialist Republics). The Korean War was primarily the result of the political division of Korea by an agreement of the victorious Allies at the conclusion of the Pacific War at the end of World War II. The Korean Peninsula was ruled by the Empire of Japan from 1910 until the end of World War II. Following the surrender of the Empire of Japan in September 1945, American administrators divided the peninsula along the 38th parallel, with U.S. military forces occupying the southern half and Soviet military forces occupying the northern half.
