Why did the North Carolina anti federalists distrust the new US government constitution?

North Carolina anti-federalists distrusted the new U.S. Constitution primarily because they believed it concentrated too much power in the federal government at the expense of states' rights. They feared that a strong central government could lead to tyranny and undermine individual liberties. Additionally, the lack of a Bill of Rights in the original Constitution raised concerns about the protection of fundamental rights. These factors fueled their resistance to ratification of the Constitution in North Carolina.
