How many jim crow laws were made, and how many are still enforced today?​

From the late 1870s Southern U.S. state legislatures passed laws requiring the separation of whites from “persons of color” in public transportation and schools. Segregation was extended to parks, cemeteries, theatres, and restaurants in an attempt to prevent any contact between Blacks and whites as equals.

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.
