And in the 20th century, we see one of the bloodiest centuries in all of human history. So let me leave you with a final series of questions. As we go into the 1800s, we talked about the various independence movements, especially in the Americas. We also have the abolishing of slavery in most of the world around this time period. And so to some degree, it looks like the ideas of the Enlightenment are coming to be. But at the exact same time, you have the age of imperialism, where more and more control is exerted over people around the planet. This all comes to a head in World War I, which is one of the bloodiest conflicts in all of human history.
