In ancient times, cities would inevitably grow to a size where the resources were insufficient to adequately insure a decent standard of living for the populace. When this happened, it was time for some of the more adventurous citizens to move on and look for another place to build a city. New SETTLERS set out, searching for a suitable site, and there establishing their new homes. The new city normally maintained ties and loyalty to the old, and eventually sent out its own SETTLERS.
