The "Lying Hungarian Prime Minister " story has been news for several days now. Thanks to Harry's Place, I've now found an interesting Hungarian English-language website with the splendid name of Pestiside
But never mind the Hungarian lies, have you heard of the "Hungarian Calendar"? It seems to be a book written by one Zoltan Hunnivari which seemingly claims that conventional history is wrong , that Jesus Christ was born in AD 194, and that basically the dates of ancient historical events are out by about 200 years. Of course, most historians would say that this is a load of old goulash.
If you want to know more, look up the phantom time hypothesis in Wikipedia , which suggests that the early middle ages (614 -911 AD) never happened.
If this isn't sufficiently weird for you, try the New Chronology of Russian mathematician Anatoly Timofeevich Fomenko, who believes that "the history of humankind goes only as far back as AD 800, we have almost no information about events between AD 800-1000, and most historical events we know took place in AD 1000-1500." Oh, and the historical figures of Jesus and Pope Gregory VII are the same person.
Wikipedia helpfully points out that "These views are entirely rejected by mainstream scholarship."
