The Appalachian Mountains acted as a barrier to further settlement to the west.
Explanation:
When the Europeans came to the east coast what is now the United States, they started to gradually settle in. More and more people were coming, the East Coast was developing more and more, but the people remained in that part, they were not moving westward. This started to cause problems as more and more people were flocking in, so the population density was rapidly increasing, and agricultural land was running low.
There was one major reason for this, the Appalachian Mountains. This large mountain range acts as a natural barrier, stretching roughly from north to south, separating the East Coast and the interior. This mountain range is pretty high, covered with dense forests, and there were numerous Indian tribes that were very angry to the white settlers, so the Europeans avoided crossing this range. It was only after the transportation improved and made the movement much easier and safer, that the people started to move in westwards.
The majority of the people that settled in the East Coast originated from:
- Great Britain
- Holland
- Ireland
