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.

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 Green...

Before we get into non-Euclidian geometry, we have to know: what even is geometry? What's up with the Pythagorean math cult? Who was Euclid, for that matter? And what the heck is the 5th Postulate?

History, and the past, can be two different concepts. Is Mansa Musa REALLY that wealthy? Did his son really die of "sleeping sickness"? It's time for Lies, featuring Robert Rath, Jac Kjellberg, and James Portnow!

1465. The Mali Empire is overextended, barely able to garrison its territory, and driven by internal power struggles. Sensing weakness, a new player emerges: the sorcerer-king, Sunni Ali.

Mansa Musa, the most powerful king in Mali’s history, is dead. He leaves behind an empire that covers half a million square miles, and he leaves a son who will only rule for four years.

Ibn Battutah wrote a book called "The Travels," producing the only eyewitness account of the Mali Empire. So today we’re going to follow him, letting his journey teach us about how trade built the realm.

In a tense battle over the fallen capital of the Ghana Empire, Sundiata's bow bends, the string twangs, and the arrow flies… or so the great epic of the Mandinka says. And from this battle, the Empire of Mali will be born.

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.

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.
