Explore how the US government hunted bison to near-extinction in the 1800s to force Native Americans onto reservations.

--

By the mid-1700s, many Plains nations survived on North America’s largest land mammals: bison. They ate its meat, made the hides into winter coats and blankets, and used the bones and horns for tools. But in the following decades, millions of bison would be deliberately slaughtered, threatening the survival of Plains societies. Andrew C. Isenberg shares what led to the animal's near-extinction.

Lesson by Andrew C. Isenberg, directed by Rémi Cans, Atypicalist.

Explore how Dutch and British colonization of South Africa led to Apartheid, the strict national policy of racial segregation.

--

For 46 years, South Africans lived under Apartheid, a strict policy of segregation that barred the country’s Black majority from skilled, high-paying jobs, quality education, voting, and much more. So, how did these laws come to be? And how did this era of institutionalized discrimination finally come to an end? Thula Simpson explores how colonization led to the national trauma of Apartheid.

Lesson by Thula Simpson, directed by Aya Marzouk, Giraffics.
