2. 2 During Period III, many connections were established among regions. These formed interregional patterns of unity. Microsoft®Encarta®Reference Library 2002. ©1993-2001 Microsoft Corporation. All rights reserved.

3. 3 At the start of Period III, numerous inventions, trade goods, and ideas were starting to spread from their regions of origin.

4. 4 … …That spread of ideas and things is part of cultural exchange. This allowed cities of the period to rise as well as decline.

5. 5 Cultural exchange had many aspects. People shared ideas across regions. Population increased and people migrated. Trade networks expanded and cities grew. Huge empires brought many different groups of people together.

6. 6 Population Ideas Trade Empires Let’s take a closer look at each of these causes of the growth and decline of cities.

7. 7 World population grew from about 250 million to 460 million between 200 CE and 1500 CE. The dip in the 1300s was due to the Bubonic Plague. Population Sometimes interregional exchanges allowed disease to spread, as well as more helpful things.

9. 9 Population growth in Afroeurasia affected the environment. Population Deforestation happened when cities and farming expanded.

10. 10 Human impact on the environment had serious effects on the ability of cities to grow. In fact, sometimes, it caused them to shrink.

14. 14 Empires Building states and empires caused declines in cities for a time, then, stability allowed cities to flourish. During Period III, many, many states and empires came… and went.
