Here is the list of the original series (the one I’m most focused on getting). I’ll cross them off as I get them; aiming to get one every two weeks, or something similar!
The ones in bold are the ones I have :]

The Angry Aztecs
The Awesome Egyptians
The Awful Egyptians
The Barmy British Empire
The Blitzed Brits
The Cut Throat Celts
The Frightful First World War
The Gorgeous Georgians
The Groovy Greeks
The Incredible Incas
The Measly Middle Ages
The Rotten Romans
The Ruthless Romans
The Savage Stone Age
The Slimy Stuarts
The Smashing Saxons
The Stormin’ Normans
The Terrible Tudors
Terrifying Tudors (formerly Even More Terrible Tudors)
The Vicious Vikings
The Vile Victorians
The Villainous Victorians
The Woeful Second World War 3 years ago

That’s where I’ll start :]
These were my favourite books as a kid (aside from Narnia and Treasure Island and all the rest of it) and given that I love the TV series so much, I can’t wait to have them all back again! 3 years ago
