Episode 10
Is drug-induced intoxication a new phenomenon – emerging in a pleasure-seeking society that knows no bounds? Discoveries of drug artifacts thousands of years old raise doubts. Intoxication seems to have been used in many cultures for spiritual insights and social rituals. Why, then, are most drugs illegal today?

Episode 11
To this day, Columbus is considered the first person to have crossed an ocean. But archaeology, genetics, and indigenous knowledge systems tell a different story: Polynesians, Vikings, and even early humans reached distant continents long before him. Why do we remember Columbus—and not them?

Episode 12
Traditions seem ancient—but many are invented, politically dictated, or shaped by modern tourism. This documentary traces the origins of traditions from Bavaria through France to Georgia, showing how customs create identity, secure power, or foster community. And it asks: If traditions are invented, why don't we simply create new ones ourselves?

Episode 13
Africa is often considered a continent entirely colonized by Europeans – although large parts of it remained independent until the 19th century. So what was it really like? This documentary tells the story of Leopold II's reign of terror in the Congo, of African-American colonizers in Liberia, and of the Ethiopian victory at Adwa. It shows just how multifaceted Africa's history truly was.

Episode 14
GPS, space travel, industrial fertilizer production: they all arose under military pressure. Wars accelerate decisions, pool resources, and drive innovation. But they also destroy knowledge, societies, and lives. Is it possible, then, to achieve progress without extreme violence?

Episode 15
The myth sounds seductive: Johannes Gutenberg invents printing – and suddenly the Reformation, the scientific revolution, and the Enlightenment begin. A single machine is said to have triggered an entire era. But historical reality is far more complex. From Chinese prototypes to conservative early printing presses, to Luther and global knowledge networks, it was the interplay of many forces that gave the printed word its historical power.

Episode 16
Did tourism originate with the railway? Pilgrimages were important precursors – but it was romantic notions of nature and the expansion of infrastructure that created the necessary conditions. Politics and media staging ultimately shaped mass travel as we know it: tourism arises when longing finds structure.

Episode 17
Are the rich today richer than ever? This episode shows how the gap between rich and poor has developed over the millennia: From the first states, through the slave trade and industrialisation, to globalised trade and neo-liberal politics. How did the rich get richer? And can the trend be reversed?
