Another link to a time line. This time the picture gives an overview of the most famous ancient civilizations and how long the endured until they got conquered or extinguished out by a stronger force.
There is also a small map in the down left corner which shows the geographic regions where the civilizations established themselves.
(The picture is quiet big so it is not possible to post it here without making it so small that it is not readable anymore. Sorry for the inconvenience!)
