The Bill of Rights was added to the Constitution because Anti-Federalists believed that they were needed in order to protect the citizens.
The Federalists were in favor of the Constitution, they felt that the Articles of Confederation was too weak and was ultimately harming the country. They wanted to ratify the Constitution, which gave power to the national government, as under the Articles the government was very weak.
The Anti-Federalists opposed the Constitution, they felt that the Articles of Confederation was fine for the country. They preferred a weak national government, as they had just broken free of British rule and were afraid of tyranny. They argued that if the Constitution was going to be ratified, there needed to be a Bill of Rights added.
While the Federalists didn't necessarily think a Bill of Rights was needed, they wanted the Anti-Federalists to agree with them, so the Bill of Rights was added to the Constitution.
I feel like everyone can agree with the decision to add a Bill of Rights. They are very important in protecting our rights and preventing the government from abusing its power on the people. They are our natural rights and it is important that they are secured.
