What groups wanted to remake or render society decades before the civil war?

After the Civil War, 4 million former slaves were looking for social equality and economic opportunity. It wasn't clear initially whether they would enjoy full-fledged citizenship or would be subjugated by the white population.

In the 1860s, it was the Republican Party in Washington — the home of former abolitionists — that sought to grant legal rights and social equality to African-Americans in the South. The Republicans — then dubbed radical Republicans — managed to enact a series of constitutional amendments and reconstruction acts granting legal equality to former slaves — and giving them access to federal courts if their rights were violated.

the conflict of this case originated when james w. mcculloch, a cashier of the baltimore branch of the second bank of the united states that the congress had chartered in 1816, refused to pay a tax imposed by the maryland state.

in the case, the state of maryland appealed that the establishment of a second bank was unconstitutional since the constitution didn't say anything about granting that power to congress. however, the case determined that even if such right wasn't specifically stated in the constitution, it was part of the "implied powers" of the government enunciated in article i, section 8.

the case also eliminated maryland's legislation to impose taxes to a national bank, asserting that even though the states retained the power of taxation, the constitution's laws are supreme and can not be controlled by the states, therefore, if a state law contradicts the constitution, it should be declared illegal.
