Why did it take so long for the congress to approve the bill of rights

The U.S Bill of Rights and the English Bill of Rights were created with one motive in mind and that was to restrict the power of the government and also provided the residents with numerous rights that are required in democratic countries. The three main similarities between the U.S. Bill of Rights and English Bill of Rights are freedom of speech, posting of bail and prohibition of quartering of troops. The main differences are that in case of English Bill of Rights, the people have the freedom of speech in Parliament, whereas in case of U.S. Bill of Rights the people have the freedom under all circumstances.
