Which American philosophy most contributed to the "closing" of the Western frontier?

Manifest destiny

Explanation:

In the year 1890, the closure of the frontier was broadcasted. what this meant was that there were no apparent tracts of land that had no settlers. Manifest destiny was an idea that the United States of America was destined by God. This idea was the continuous expansion of all boundaries of the United States towards the Pacific West and past it.

both are true, the congress does have the power to create banks, even if this power is not specifically described in the constitution, since there is nothing restricting it and there is power given to the congress to make "all laws which shall be necessary and proper". maryland was not allowed to tax a branch of the national bank operating there, and the supreme court decided that no state could. both of these topics were discussed in a decision of the mcculloch v. maryland case in 1819.
