The answer is competition
The idea of manifest destiny greatly helped shape the U.S. governments's policies of land acquisition, since this held that the US was "destined" to expand from the Atlantic Ocean to the Pacific--meaning that the US embarked on a series of wars with Mexico and confrontations with Natives that helped the settlers move west.
Simple definition in my own words would be to build relationship with someone, For example social studies or History, the colonists would take helps from the natives which is example of alliance, which is to build a relationship with someone or some people that you are not used to and/or don't know.
