Explanation:

The Anti-Federalists explained the United States Constitution because they thought that it passed too much jurisdiction to the central state. They found that the untested form of government would have different results in the country. The Anti-Federalists probed the Constitution for its absence of Bill of Rights, and they argued it would be the end of all forms of self-rule in the American kingdoms.
