The Rise of Civilizations

Civilizations began to rise in river valleys.  The first four civilizations were located in the Tigris & Euphrates River Valley, the Nile River Valley, the Indus River Valley, and the Yellow River Valley.  The Sumerians, in the Tigris & Euphrates River Valley, gave us the first form of writing, known as cuneiform.  This coincides with the beginning of the Bronze Age and the beginning of history.
