18. Good suggestion for the reasons you gave.

The same thing about territory changing with the ability to occupy and defend land is true of political nation states as well. Look at maps of Europe over the centuries since the Roman Empire ended to see how much their boundaries have changed, not to mention some that just no longer exist, like Prussia. In the present day, look at Ukraine fighting Russia for its existence.

I would include another reason for having a time lapse map. People's territories changed over time as European settlers took over Native land. That was the main reason for the wars between Native people and colonists/settlers. When New England colonies expanded, the Native people on the land were pushed farther west or north into other tribal territories. They had to negotiate with other tribes for living space. That led to the Native alliance under Metacom, aka "King Phillip," that nearly pushed the NE colonists out of North America. Metacom was the son of Massasoit, the chief who had been aligned with the Pilgrims. But continual land encroachment and crowding of Native people led to open war.

The same thing happened over and over with other tribes and territories as Americans moved westward.
