Mongols T-Shirt: http://store.dftba.com/product....s/crashcourse-mongol

In which John Green teaches you, at long last, about the most exceptional bunch of empire-building nomads in the history of the world, the Mongols! How did the Mongols go from being a relatively small band of herders who occasionally engaged in some light hunting-gathering to being one of the most formidable fighting forces in the world? It turns out Genghis Khan was a pretty big part of it, but you probably already knew that. The more interesting questions might be, what kind of rulers were they, and what effect did their empire have on the world we know today? Find out, as John FINALLY teaches you about the Mongols.

Our next stop on our tour of ethics is Kant’s ethics. Today Hank explains hypothetical and categorical imperatives, the universalizability principle, autonomy, and what it means to treat people as ends-in-themselves, rather than as mere means.

This week on Crash Course Economics, we're talking about monetary policy. The reality of the world is that the United States (and most of the world's economies) are, to varying degrees, Keynesian. When things go wrong, economically, the central bank of the country intervenes to try aand get things back on track. In the United States, the Federal Reserve is the organization that steps in to use monetary policy to steer the economy. When the Fed, as it's called, does step in, there are a few different tacks it can take. The Fed can change interest rates, or it can change the money supply. This is pretty interesting stuff, and it's what we're getting into today.

2,000 Years of Chinese History! The Mandate of Heaven and Confucius:
Crash Course World History #7

In which John introduces you to quite a lot of Chinese history by
discussing the complicated relationship between the Confucian scholars
who wrote Chinese history and the emperors (and empress) who made it.
Included is a brief introduction to all the dynasties in Chinese
history and an introduction to Confucius and the Confucian emphasis on
filial piety, the role the mandate of heaven played in organizing
China, and how China became the first modern state.
