The "Hitler Diaries" are a collection of forged documents that were purported to be the personal diaries of Adolf Hitler. They were first published in 1983 by the German magazine Stern, which claimed to have acquired them from a private dealer. The diaries contained entries that detailed Hitler's thoughts and experiences during World War II, but they were later revealed to be fakes. The forgeries were created by Konrad Kujau, a German artist and conman. After extensive investigation, experts confirmed that the diaries were not authentic, leading to a major scandal in the media. The incident highlighted the challenges of verifying historical documents and the impact of misinformation.
