1993. The first year with a Horrible Histories book published in it. The first two Horrible Histories books: Terrible Tudors and Awesome Egyptians we could have never done without. Without these two books we would be without Horrible Histories, The Show, the cartoon, the magazine, and the great spin-offs: Horrible Science, Murderous Maths, Horrible Geography and lots more would have never been published if it wasn't for Terrible Tudors and Awesome Egyptians. Soon after, more books were published. The third Horrible Histories Book was Blitzed Brits. Ten years after 1993, the 10th Anniversary of Horrible Histories was celebrated by the book, The Horrible History of The World. Then, 19 years after 1993 was 2012. A lot of change in time with Horrible Histories books. This year is the 20th Anniversary. 2013.
