DBQ. Us history.

I have to categorize my essay. For example: social, economic, and political. I was wondering if it’d be okay for my categories to be cause and effect but the statement I have to prove or disprove (I’m proving it) is “From 1820 to 1860, the concept of Manifest Destiny played a major role in American politics.” So could I prove that statement by using cause and effect?</p>
