Answer: No
Explanation: The United States Constitution and Bill of Rights did not explicitly promise to either undermine or strengthen slavery in the United States. However, the Constitution did include several provisions that were relevant to the institution of slavery, and its interpretation and application over time had significant implications for the fate of slavery in the country.
The Constitution included several provisions that were relevant to slavery, such as the Three-Fifths Compromise, which counted slaves as three-fifths of a person for purposes of determining representation in Congress. Additionally, the Constitution included a Fugitive Slave Clause, which required that escaped slaves be returned to their owners. These provisions reflected the reality of slavery in the United States at the time, but did not necessarily strengthen or undermine the institution itself.
The Bill of Rights, which consists of the first ten amendments to the Constitution, did not directly address the issue of slavery. However, several of the amendments in the Bill of Rights, such as the Fifth Amendment's guarantee of due process and the Eighth Amendment's prohibition on cruel and unusual punishment, have been interpreted as having implications for the legality of slavery and the treatment of enslaved individuals.
Over time, the interpretation and application of the Constitution and Bill of Rights had significant implications for the fate of slavery in the United States. While the Constitution did not explicitly promise to either undermine or strengthen slavery, the debates and conflicts over its interpretation and application ultimately contributed to the growing political and social tensions that led to the Civil War and the eventual abolition of slavery in the United States.
