AP World History Review: The Agricultural Revolution: CrashCourse World History #1, Key Concept 1.2 (11:10)

In this first video of the series, the movement from foraging, hunting, and herding of early civilizations to agriculture is the subject of discussion. The Agricultural Revolution attached people to specific regions, unlike earlier foragers that roamed for food. Agriculture helped feed more people, even if at the expense of the environment through irrigation, oil drilling, and soil depletion.

While the causes of the Agricultural Revolution are uncertain–whether from population pressure, experimentation, or accident–one thing remains clear. The advent of agriculture brought not only planetary changes but cultural ones: patriarchy, slavery, famine, and war, to name a few. This first video concludes with a definition of ‘revolution’.

Indus Valley Civilization: CrashCourse World History #2, Key Concept 1.3 (9:34)

Continuing the exploration of early civilization formation, the Indus Valley provides the perfect subject to examine the term ‘civilization’. What makes a civilization? Some markers include surplus production, cities, specialization of labor, social stratification, religion, government, writing, and rivers.

One such civilization located on the Indus Valley floodplain flourished around 3,000 BC. The largest civilization, with over 1500 sites discovered by archeologists, reveals rather sophisticated cities with plumbing, sewage systems, and a central, public bathhouse conjectured to be a place of ritual purification.

Evidence of indecipherable seals indicates the peaceful Indus Valley inhabitants traded with Mesopotamians. Why did the civilization end? Why does any civilization begin? These concluding questions and speculations round off this second video.

Mesopotamia: CrashCourse World History #3, Key Concept 1.3 (12:05)

CrashCourse video number three covers Mesopotamian and Assyrian civilizations. The first concept discussed as the foundation for this section is the competing interests of cities and country. Identities formed around cities, where water supplies and natural advantages affected people’s lives the most. Situated on the Tigris and Euphrates Rivers, Mesopotamia suffered intermittent and violent flooding, which made life chaotic.

Power held by priests able to placate capricious and vengeful gods eventually shifted to mighty kings who conquered in the name of the gods. Meanwhile, writing, such as cuneiform, was used to record trade transactions, create class distinctions, and document history.

Socialistic economic orders gave way to free enterprise economic orders, while taxes afforded stable social orders. The Hammurabi laws and code furthered the shift of power from the gods to men, and eventually, Assyria, Mesopotamia, and Babylon fell to nomadic invaders or defeat in battles.
