What is the historical background of the US federal court system in the US?

The U.S. federal court system was established by the Constitution in 1789, which created a framework for federal judiciary to interpret laws and resolve disputes. The Judiciary Act of 1789 further organized the system, creating district courts, circuit courts, and the Supreme Court. Over time, the judiciary evolved through landmark Supreme Court decisions and legislation, shaping its structure and authority. The system reflects the principles of federalism, balancing power between state and federal courts.
