The History of Non-Euclidian Geometry - The Great Quest - Extra History - #2
For hundreds of years, Euclid's geometry disappeared with the fall of the Roman Empire. But in Constantinople, Islamic mathematicians, including Al-Khwarizmi (who gave us the word "algebra") worked long and hard on proving the Fifth Postulate.
And the winner is...
The Viking Expansion: From Constantinople to Canada will air later in 2018!Around 1000 CE, Leif Erikson stepped onto the shores of North America. But his settlements there were only the furthest-flung outposts of the Norse expansion. Centuries of raiding, trading, and light invading had spread Northmen from Byzantium to Greenland—and left legacies we can still see today.

The Danelaw - The Fall of Eric Bloodaxe - Extra History - #2
After peace was made between King Alfred and Guthrum, the Danelaw was born--a geographic area in England controlled by the Danes, but also extremely reliant on the cooperation by the Anglo-Saxons and the local Christian population.Sponsored by Total War Saga: Thrones of Britannia! http://store.steampowered.com/app/712100/Total_War_Saga_Thrones_of_Britannia/

Behind the scenes: The Danelaw
We'd like to remind everyone that no characters are harmed in the creation of our videos, not even in our most brutal Extra History episodes. Courtesy of Scott DeWitt:
The Triangle Shirtwaist Fire - Horror in Manhattan - Extra History
A throwaway cigarette landed on a pile of cloth. 146 workers died from the resulting fire. But this tragedy motivated citizens and politicians to take a stand from workers' rights, creating a far safer world that we still live in over a century later.
The Danelaw - Alfred vs. Guthrum - Extra History - #1
The year is 865. Dragon ships push up on the shores of East Anglia. But this is no raid—it’s the Great Heathen Army. They’re not here for treasure. They’re here to found a nation.Sponsored by Total War Saga: Thrones of Britannia! http://store.steampowered.com/app/712100/Total_War_Saga_Thrones_of_Britannia/
