When two or more groups settle into the same area, anything can come of it. Some people will get along better than others; however, if it is anything like the European settlers and the Native Americans, there may be some serious conflicts between the groups. A more modern day connection I can make to this is when you start living somewhere and you have to live with a roommate.
Some benefits of two or more groups sharing the same living space is trade and/or collaboration. At first, the Natives and Europeans lived together in harmony and traded goods and lived normal lives. Also, In my opinion, if they would have been able to look past their differences, they could have worked together in building our nation.
Sometimes, however, settling together can cause major discomfort, especially if you are nothing like the other group of people. In the case of the Europeans and the Natives, they lived very different lives and had different beliefs. At first, they lived together in harmony and traded goods and lived normal lives. After some time the Europeans wanted to expand and they took lots of the Native Americans' land. This led to many feuds and they resented each other for most years. Another reason the two could not get along was because the Puritans could not convert the Natives to their religion, and they ultimately declared them to be demonic. Since the Puritans had such strong beliefs, there was no way they could live with each other in peace.
These points can both connect to living with a roommate because if you get along great with the person you live with, everything in life will occur smoothly. On the other hand, still going along with my modern day connection, if you can't stand the person you live with and there is just constant fighting among the two of you, everyone's lives are going to be just that much harder and someone might even end up leaving the area. So overall I think sharing the same living space can have its pros and cons.
