The 13 original states wrote up their constitutions prior to the Federal Constitution and the inclusion the Bill of Rights.
Missouri was not one of the original 13.
Only two current State Constitutions in place predate the US Constitution. Massachusetts (1780) and New Hampshire (1784).
Missouri was not one of the original 13.
Regardless of whether Missouri was one of the original 13 states, the Constitution makes all states equal. Also, the 14th amendment requires all state laws and constitutions to comply with federal standards for civil rights enumerated in the US Constitution. Even thought the US Constitution bill of rights only applied to how the federal government treats citizens, the 14th amendment applies those and subsequent standards to the states.
