The correct answer to this open question is the following.

The forces that tended to unify Americans in the early 1800s were the sentiment of pride and nationalism to be a United States citizen. The common bond was the hard work and sacrifice to overcome difficult situations and thrive. Some of the important points of disagreement were regarding the westward expansion. With the purchase of the Louisiana Territory by the government of Thomas Jefferson, the United States was about to explore new frontiers to the west of the country. The occupation of new lands created some differences. Immigration was also a point of controversy. Some people had no trouble welcoming European immigration but others saw this as a threat to their jobs, culture, and traditions.
