The generality of Article III of the Constitution raised questions that Congress had to address in the Judiciary Act of 1789. These questions had no easy answers, and the solutions to them were achieved politically. The First Congress decided that it could regulate the jurisdiction of all Federal courts, and in the Judiciary Act of 1789, Congress established with great particularity a limited jurisdiction for the district and circuit courts, gave the Supreme Court the original jurisdiction provided for in the Constitution, and granted the Court appellate jurisdiction in cases from the Federal circuit courts and from the state courts where those courts rulings had rejected Federal claims. The decision to grant Federal courts a jurisdiction more restrictive than that allowed by the Constitution represented a recognition by the Congress that the people of the United States would not find a full-blown Federal court system palatable at that time.
For nearly all of the next century the judicial system remained essentially as established by the Judiciary Act of 1789. Only after the country had expanded across a continent and had been torn apart by civil war were major changes made. A separate tier of appellate circuit courts created in 1891 removed the burden of circuit riding from the shoulders of the Supreme Court justices, but otherwise left intact the judicial structure.
Answer: Well, during the Reconstruction Era, black code laws were adopted by southern states after the Civil War to control (or reimpose) the old social structure. Southern states passed laws that restricted the civil rights of the emancipated former slaves. so basically during this period they tried to reintegrate southern states from the Confederacy.
