One of the rationales for overseas colonization was the need to bring primitive peoples to christianity. how successful were the colonists in these efforts?

If success is to be measured by number of converts, then the colonists were extremely successful. In the case of England, they successfully brought Christianity to many Native American people in the Americas. They also spread Christianity throughout Africa. Other colonists were extremely successful too, in particular the Spanish missionaries. To this day, areas that were colonized by Spain such as the Philippines and Latin America are some of the most Christian regions on Earth.

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.
