In this video Heimler reviews Unit 2 of the AP World History curriculum. The main bulk of the review consists of comparing the three major trade routes during the period 1200-1450: the Silk Roads, the Indian Ocean Routes, and the Trans-Saharan Trade Routes.

Each of the major trade routes had much in common. They connected distant societies by trade and had significant secondary consequences. In addition to merchants carrying goods for sale, they also carried important cultural, environmental, and technological goods that they introduced to the various cultures in which they found themselves.

Some major technologies that arose to facilitate trade are as follows: the saddle, the lateen sail, the sternpost rudder, the magnetic compass, and the astrolabe.

Additionally, because large states kept the trade routes relatively safe, travelers like Ibn Battuta and Marco Polo helped expand people’s imaginations for lands far beyond their own.

And, of course, we have a look at the most significant pastoral people ever to take the stage of world history: the Mongols. They were largely responsible for the security of the major trading routes and, on the negative side, the spread of the Black Death.

This video tells you all you need to know about Unit 2 (1200-1450) for AP World History. Let me know if you have any questions.
