The most saddest:Human zoos - one of Europe’s most shameful secrets, ended in the ’50s.

Barely some few years back, people from Belgium, France and many other countries came to visit humans,  caged and exhibited in front of a large audience and thrown in with animals at their local zoo.

The number of Human zoos were numerous and  were found around Europe in the late 1800s to the mid 1900s. However, they weren’t the only continent that liked to expose humans in this way. North America, specifically the U.S., had their fair share of human zoos
