Answer: Black Americans and Women
Explanation:
When the Constitution was drawn up in the Constitutional Convention, certain groups were not catered for.
One of those groups were Black Americans. At the time, the southern economy was heavily dependent on slave labor so they did not want the enslaved people to gain freedoms and fought against it. They denied them the right to vote as well and during censuses did not count them as full human beings.
Some of these injustices were reversed after the Civil war but racial inequality was openly practiced for a long time afterwards until reforms at a Federal level (such as the Civil Rights Act) reduced most of them.
Women also were disenfranchised in a very patriarchal society. They were not allowed to vote and could not even some political offices. This led to the Suffrage movements of the 19th and 20th centuries that eventually got Congress to pass laws allowing women to vote. Congress has since then passed more laws aimed at reducing and eliminating discrimination on the grounds of being a woman since then.
